Molten Core!

[MongoJerry]

You should also make it a requirement that everyone downloads and installs CT_raidassist from http://www.ctmod.net/ It's fantastic. It lets everyone in the raid see everyone's health, mana, buffs, and debuffs. In addition, it now has the mana conserve feature built into it, so that priests can set it up so that healing spells get interrupted at the last moment if the target is above a percentage of health that you have set. (I have mine set at 85%). However, for your stats to be broadcast to the raid, you need to have it installed, so it's important that everyone -- not just priests -- install it. (Yes, yes, there is a way to broadcast the health and mana of the people who are in your party who don't have it installed, but it doesn't broadcast the debuffs, which are the most important things in Molten Core. It's far better to make sure *everyone* has it installed).

Second, you should have as a requirement that everyone gets either teamspeak or ventrillo (whichever kind of server you want to use) and that they get on it. It's so much easier to coordinate everything by speaking than it is using the text chat window, and when situations change (e.g. the main tank goes down or you get an add), it makes it so much easier to fix things. Not everyone needs to have a mike, but everyone should be able to listen to instructions over teamspeak/ventrillo.
