Maybe a good idea to make fixed raid days, like ICC every friday night at 3:00 PM Server Time...
this way we get both more interaction between guild members and you dont have to keep looking all the time if someone might go somewhere... Also, we shoul make fixed days not only for instances that drop good gear (ICC, Ulduar Naxx etc.), but also classic and TBC raids, because as a raid/pvp guild we should try to make sure that everyone who wants it, can get the dungeon and raid master achievements (all raids from classic/TBC)
I was thinking about making 1 day in the week the "Weekly pre-WOTLK Raid Day", in which we can do for instnace Ahn'Qirai, Tempest Keep, Gruul's Lair, and maybe Black Temple if enough people are willing to go somewhere
