Hi
We have players from Europe, the US and Australia. Though I have to admit most of the activity is around midnight, Europe time, you will find people playing all around the clock. But yes... at your midnight the activity may be somewhat low.
Anyway - I suggest just give it a shot and see how it goes. Worst case you'll feel very alone and hate it. New players are always welcome though, and I for one can attest that this is a fun bunch of people to play games with!
PS: Lynch this Graeham fellow. He's evil. Probably. /s
