This would seem somewhat reminiscent of the old BotM, IMO. Someone could actually just do nothing but work on one Fraxy project for two months and claim that that's there entry, and there's more or less no way we'd be able to call them out on it. That being said, I DO like the idea of a constant, predictable stream of contests. I think it'd encourage people to actually do stuff in the game, and I'd try to join on the off chance that I can afford to neglect stuff like I did for this Quickboss, so I'll vote yes.
EDIT: And after immediately posting this and voting, I saw that changing the times up was an option. So I vote for that instead! (Take one away from "Yes" and add it to "Change Time in Between"
