 - E2a1+) [RECOMMENDATION] If a judge finds a submitted solution that does not appear to have information to identify the attempt, they should check both sides of the paper.
 - E2b+) [CLARIFICATION] A competitor may choose to stop an attempt early by handing in a solution before the time limit.
 - 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+) [EXPLANATION] A competition registrant ID is an identifier (e.g. a number) assigned to a competitor for the competition. Some competitions use this to keep track of score sheets and enter results.
 - E2c1+++) [EXPLANATION] The competitor is not required to write the competition name, round, and/or attempt number on their submitted paper, but may wish to do so in order to help the organization team keep track of submitted solutions.
 - 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 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 moves and writing moves above that are clearly meant to replace them, moves written in subscript or superscript to fit between other moves).
 - E2c2++) [REMINDER] In the past, bracket notations (e.g. [r] or [u2]) were permitted for Fewest Moves. Only rotations based on x, y, or z are permitted now (see [Regulation 12a4a](regulations:regulation:12a4a)).
