ok, we've been having some success with having more humans playing lately. this is good! the time this seems to be happening regularly is around 1 p.m. c.s.t (cental time). this generally goes till about 3 p.m. c.s.t. when a lot of the euro's take off to bed or whatever. so, if you cant make it any other time, and are looking to play with a lot of AR members, this is a pretty good time during the week.
on weekends it's different. it's usually earlier in the day, like in the morning some time, but i havent got a full handle on the weekends yet.
so, if you're looking to play on weekdays, especially with the europeans, around 1 p.m. central time is generally pretty good.
