I'm german (gmt+1) so I think it'd be best if you were online around 2 pm (-> evening for me).
I don't think I'll be online at the weekend, but Mo/Tue would be fine I guess.
Wait, so they just now decided to assign me to someone, freaky. Alright, well I can use IRC, but its through a web client. Do you have any alternative methods of contact, like AIM or skype?
