If you're gonna be making your own sigs, at least check out the guidelines where they say not to do that. But hey, more power to you!
As for this forum not having sigs:
I'm glad they don't have it, in a way. Because the forum I used to be on had sigs, but they didn't have the image BBcode and what not, so the only sigs could be short text blurbs. With the ability to have image sigs, I'm glad we don't have access to them at all.
Give me a nice clean forum where I can actually read the posts without sifting through pages of flashing, moving, colorful pictures.
