Adium Theme? and i wounder one thing too. I have in the end of November got my first iMac and been a Macuser. and i wounder about the application Candycar that i see you use. How much performance that require?
The adium theme I just changed the colors in adium preferences and the font I dont think you have to worry too much on performance as the app only changes your icons and it does not stay open all the time .
what settings? i want to have same Message Styles / config like yours. Do you thick that? I shall buy and install Candybar tomorrow or some day in the week. Then I came on if you're going to have some more eyecandy on the computer so you get all sacrifice a little (;
