Based on the poll, we've picked Tuesday and Sunday at 8:30 (server time) for our designated Kara nights (post is here: http://www.thelollipopguild.com/forums/showthread.php?t=1781). We wanted one weekday and one weekend night as not to nerf anyone's RL weekend fun.
We'll be scheduling with GEM (in the AlleriaUnited channel) and try to form a balanced group, favoring those that signed up first. Hate to have disappointed people though, so we'll do our best to incorporate everyone who signed up at least one run a week if possible. And if we get big enough, we'll start a second team.
Let me know if you have any questions or concerns about the plan, and I'll see you all in Azeroth!
