Ok, let's see how this works out.
I'm gonna play tonight (or today, or tomorrow depending on where you are located) at these times:
1800 GMT (2000 CET DST, May 23)
and
0000 GMT (0200 CET DST, May 24)
Not sure about the US or asian, or australian timezones, sorry.
I'll try to say on for a while (a couple of maps), and see if someone joins in. Owning bots gets old really fast, and my friends are mostly bogged down by diapers and work nowadays, so I put my trust in you guys.
Just leave a note here if you know you can be on at these times.
EDIT: according to this: http://www.worldtimezone.com, 0000 gmt corresponds to 7 pm, CST DST, May 23. And 1800 gmt is 11 am, may 23.
