I pretty much figured that the ideal time would have to be during the weekend. We don't have to make a clan in order to play, but it will make it much easier to get a hold of everyone who is online and what have you. It would definitely be more helpful.
If you wish to participate, give a time and day when you are available and we'll advise! As I said, I suppose Saturday/Sunday is best for all, but we shall see.
Everyone should give an ideal time and we will work it out from there.
edit: Regarding the SC2 mod community, I have no clue. I know it is not non-existent but I'm not sure whether it is really big or not. I'd have to say decent sized, possibly as big as WC3 considering the fact that SC2 has more players on average (1m/1.5m on every day, if I recall WC3 had somewhere between 700k-1m for most years and then more like 300-500k toward the end).
