Not necessarily 1st May, it could be on some other day as well.
Anyway, what I mean to say is, this will be the day where every post that is posted will be dire. No one will post anything sensible, only dire. There will be no restrictions to what you write as long as it's dire and complies with the forum rules.
Dire, dire and dire. This is how the forum will be.
Maybe we can restrict the direness only to OT or one particular thread, but we should go for it. After all, dire is the most popular word on CW Forums. And we can celebrate the day every year as well.
