Quick question about signatures?

[ohdollypop]

Alright, call me an idiot.

I am new to Greek chat. I'm an alum of my sorority, and would love to put my letters in my signature, but I can't figure out how to change the font, color, etc. How do you all do it?

I'd appreciate any advice...sorry if this doesn't go here, I looked around and couldn't find any place else to post it that wasn't completely out of character with the rest of the threads.

Thanks!
