Ryan:
I added a bunch of avatars to the gallery section of the forum - click on your profile, go to the bottom of the page, choose gallery, then gallery3 and you'll see the dancing alien and a lot of other new avatars there, you can add them and any images you have in your profile or signature.
I do have a generous signature allowance of 2000 characters, the default is 225 characters, so thats about 9 times larger than default, you should be able to have a creative signature with THAT kind of space - the only thing I ask is to keep BIG IMAGES out of the signature.
Look at my signature and you will notice the big red dot and the text are ALL ONE IMAGE - the text looks like it's text, but it is actually a transparent GIF image of text with the ball part of that image. The dancing alien is a separate animated GIF image to the left of the ball/text image. That and my links to my different pages, etc make for a sizable signature, but it isn't too TALL, so it doesn't cause people to scroll and scroll to much.Besides, I never post short posts - lol. I've never been blamed of "one liners" I just don't have that in me

I'm more into quality than quanity when it comes to posting - I hate to see my RED DOT SPECIAL come up too frequently in the same post, so long replies it is!
