Aliases – I have never played a game, MMO or MUD, which did not have an alias feature. Considering the amount of text I enter, much of which is repeated on a regular basis, this is a must have feature. Extra credit will be given if the alias can contain color. Extra Extra credit: I write songs about the games I play. I sing the songs in the game. If I could have a macro that could contain an entire song and print out a line every 30 seconds or so, that would be awesome.
On a related note, the excessive message warning seems to be -much- easier to trigger now. I generally start to get it 3/4 of the way through a song. I also have a char who is a hyperactive girl and with her, I get it -all- the time.
