The counter on my signature is from a site that many of our VJers used. It's a long string of either HTML code, or BB Code. I had to play around with my signature window, switching from standard editor to rich text editor. Then, I also had to play around with viewing my window in HTML source. It was horrible. I finally got it to work.
The problem that happened with just copy and pasting the code from that site will always give me a signature too long error code. Don't know why. Looks like I found a bug in the signature window.
