How did I do it? Easy! When you reply, look above the smilies. One of the tags is an m with an arrow (<-M , very close to that). This is the marquee code. Now, just repalce the word "STUFF" with your text, or in my case, cheesy smiles! (or any other smiles!)
And Say, I was just teasing you. I'm a little hyper on these boards lately (can't you tell?)
