Sep 3rd 2008 7:23PM I suspect that the mechanics of the warlock epic mount encounter will prevent it from being soloed, regardless of level. You need somebody else to take care of the spawning mobs while the warlock keeps the bell, wheel and candle active. Any damage to the warlock interrupts the process, and the ritual fails if all three items become inactive.

It keeps a local database of names, with a negative/neutral/positive rating system and a field for comments. It also will colour the names of people in chat and the LFG interface if they have a negative (red) or positive (green) rating.
I find it's really valuable for reminding me about people who sucked or were just plain unpleasant to run an instance with - obviously you don't want to put them on your friends list, and you might not want to use the ignore list for this purpose.
