In reference to last year. http://us.battle.net/wow/en/forum/topic/3229035010
I usually try not to do it the day of Halloween, because people usually have plans, parties, kids..etc
This year Halloween falls on a Wed. I don't know when I'll do it. The expansion comes out Sept 25, thats only a month in. Most people will likely be raiding on a Wed. May the Monday before or the weekend before, Sat?
Normally I organize the Horde side. The first year Hood organized the ally side. The second year he had quit wow by then, so I recruited Ranwalk to organize the ally. Ranwalk is now horde.
I need a well known alliance player who is able to communicate with me (which mostly means me yelling alot, cause people in large groups are impatient and don't listen to instructions) and hold the attention of lots of impatient people. Usually, I start off with a 40 man raid group, if theres more interest I put someone in charge of that group and start another raid group.
So I need a few helpers on horde side, a leader and a few helpers on ally side.
