I'm with Mark Thorpe on this one. Here's my 2 cents:
This is a computer forum for learning/showing/discussing everything about computers. If you want to get artsy and creative, go use MSPaint. But for a forum where its sole purpose is for discussion, why do we need colors and sizes and fonts? Here's a guy who knows all about this: Maddox. Bottomline: Keep it simple, its more effective.
Also, Ace, your sig says "If it isn't broke, don't fix it." Hmmm.....
On a sidenote: I'm sure Mac forums have all that artsy font stuff that you guys want, if you want to check that out.
