I don't really care since I don't participate but it's easy to say any time is a bad time.
May = GL having quality maps by then. Sure it's possible but more time is always better. I'd personally like to see some interesting maps for dfwc.
June/July/Aug = Summer / People not wanting to sit at their computers
Sept/Oct/Nov = School
Dec = Holidays/Traveling
There you have it. Looks like we can't have DFWC at all!
/sarcasm end
Just vote for the times u have available and whoever's in charge can accommodate the majority. Not going to be able to please everybody.
