Proto-Proposal: Mark decay (AI = 2, please) Amend the rule "Marks" by appending this text to the list of ways to gain and lose Marks:
(-*) Two seconds before the end of each month, each entity loses
eir holdings of each color of Mark, rounded down to the
nearest multiple of 100; for each 100 Marks of a given color
that e loses, e gains 1 VC of that color.
