 - E2b+) [CLARIFICATION] A competitor may choose to stop an attempt early by handing in a solution before the time limit.
 - E2a1+) [RECOMMENDATION] If a judge finds a submitted solution that does not appear to have a name, they should check both sides of the paper for a name.
 - E2c+) [CLARIFICATION] Although the judge may provide a standard sheet for competitors to submit solutions, a competitor may submit a solution on a different piece of paper. (Note that the piece of paper must come from the judge, according to [Regulation E3a](regulations:regulation:E3a).)
-- E2c1+) [ADDITION] If the competitor forgot to write their name on their intended solution paper before the time limited, they are permitted to add their name in front of a judge. In this case, the competitor must ask the judge while submitting their solution and then immediately write their name (and make no other changes) under direct supervision of the judge. Once a competitor has finished submitting their solution (e.g. placing it in the judge's hands and allowing the judge to move on to the next competitor, placing it on the judge's table and walking away), they are not permitted to add their name. If the competitor writes their name after the time limit but before asking the judge, the attempt remains disqualified (DNF).
-- E2c1++) [ADDITION] If a judge finds a solution without a name after the competitor has finished submitting it (e.g. while grading the attempt), they should find out the competitor who wrote the solution in order to assign them a DNF (rather than DNS). However, they must not allow the competitor to add their name at this point (i.e. the competitor must receive a DNF result).
+- E2c++) [CLARIFICATION] The competitor does not need to write information to identify the attempt (i.e. competition name, round, attempt number), but may do so in order to help the organization team keep track of submitted solution.
+- E2c1+) [ADDITION] If the competitor forgot to write information to identify the attempt on their intended solution paper before the time limit, they are permitted to add the information in front of a judge. In this case, the competitor must ask the judge while submitting their solution and then immediately write only the relevant information (and make no other changes) under direct supervision of the judge. Once a competitor has finished submitting their solution (e.g. placing it in the judge's hands and allowing the judge to move on to the next competitor, placing it on the judge's table and walking away), they are not permitted to add the information. If the competitor writes the information after the time limit but before asking the judge, the attempt remains disqualified (DNF).
+- E2c1++) [ADDITION] If a judge finds a solution without a information to identify the attempt after the competitor has finished submitting it (e.g. while grading the attempt), they should find out the competitor who wrote the solution in order to assign them a DNF (rather than DNS). Note tat the competitor must not be allowed to write information to identify the attempt at this point, so they must receive a DNF result.
 - E2c2+) [EXAMPLE] Examples that are not considered a single unambiguous move sequence: multiple solution sequences without exactly one clearly indicated solution, a solution with ambiguous symbols (e.g. a letter that looks similar to "B" and "R" but is not clearly one or the other), a solution with stars or long arrows indicating moves to be performed out of written order (e.g. "insertions" that are not written in-line with the rest of the move sequence, "pre-moves" that are not incorporated into the move sequence using valid notation), a move sequence that is not written out roughly as a series of lines in reading order, any arrangement of symbols that cannot be interpreted as an unambiguous move sequence. Exceptions to the examples above: small typographic corrections (e.g. blacking out a move and writing a move above that is clearly meant to replace it, moves written in subscript or superscript to fit between other moves).
 - E2c3+) [ADDITION] A blacked-out move or symbol should be covered using ink in a solid rectangle, oval, or other filled shape. A partially filled shape or scribble is permitted as long as it clearly covers the symbol, at the discretion of the judge. If a move is not clearly scribbled out and it is not clear whether the move is part of the solution, the judge should consider it an ambiguous move sequence (see [Regulation E2c2](regulations:regulation:E2c2) and [Guideline E2c2+](guidelines:guideline:E2c2+)).
 - E2c4+) [CLARIFICATION] Examples of symbols or combinations of symbols that are not permitted in solutions for Fewest Moves Solving: M, e, r, Y (uppercase), T, U1, Ui, U3, U-, R++, R2', R'2, L'w, 1R, 2U, 2f, 2-3r, 1Rw, 3Rw, 2-3Rw, rw, Rr, *, →, ⮐, /, ., ?, [r u], [F], <f>, {f}, [f]', [f]2, [x], (x), (L), 2(Rw), (U)2, (U)', (R U)', (R U R'), [R, U], [R: U].

 - E2) Procedure for 3x3x3 Fewest Moves:
     - E2a) The judge distributes a scramble sequence and paper to all competitors. The judge then starts the stopwatch and calls "GO".
-        - E2a1) The competitor must not write on any paper before the attempt has begun. Exception: the competitor may write their name once on each piece of paper before the attempt. If they write their name on the paper with the scramble sequence, they must write it on the back.
+        - E2a1) Before the attempt has begun, the competitor must not write on any paper intended for the attempt. Exception: the competitor may write information to identify the attempt [Regulation E2c1](regulations:regulation:E2c1). If they write this information on the paper with the scramble sequence, they must write only on the back side before the attempt.
     - E2b) All competitors have a total time limit of 60 minutes to find and write a solution.
         - E2b1) The judge should call "5 MINUTES REMAINING" at 55 minutes, and must call "STOP" at 60 minutes.
-    - E2c) At 60 minutes, each competitor must submit to the judge a single piece of paper with the competitor's written name (optionally accompanied by WCA ID) and solution.
-        - E2c1) The piece of paper must clearly indicate the competitor's name. Penalty for a submitted solution without a name: disqualification of the attempt (DNF).
+    - E2c) At 60 minutes, each competitor must submit to the judge a single piece of paper with a written solution and information to identify the attempt.
+        - E2c1) Information to identify the attempt is: the competitor's name or WCA ID (at least one, optionally both), and optionally the competition name, round, and/or attempt number. Penalty for a submitted solution without a name or WCA ID: disqualification of the attempt (DNF).
         - E2c2) The solution must be a single unambiguous move sequence with each individual move written out in sequential order. Penalty for an ambiguous solution: disqualification of the attempt (DNF).
         - E2c3) The competitor should clearly black out/scribble out all moves on the paper that are not part of their intended solution.
         - E2c4) The competitor's solution must only use moves that are exactly defined as notation for the 3x3x3 Cube in [Regulation 12a](regulations:regulation:12a), and must not use any symbols or combinations of symbols that are not specifically defined there. Penalty: disqualification of the attempt (DNF).
