It's kind of a confusing thing...  But i'll do my best to explain it.  Haha.

Okayy, well first look on your screen, below the navagation bar [[Home, About, Media...]] and you'll see bunch of icons.  One's two people, the other is a wheel-ish type thing [[can't think of what it's called right now]], then there's one with a green person and an envelope....  Well, click on the wheel thing.  It's gray and the second one you'll see. 

Once you've clicked that a screen will pop up that has levels to it.  [[You'll see what i mean when you're there]].  Scroll down until you see a level called 'User settings' and click the little plus sign next to it.  The section will drop down and you'll see 'Group View,' 'Threads Per Page,' 'Signature,' and on and on.  You want Signature.

There's an empty box in that section and you put your HTML code into it.  An HTML code is that code that starts with < a href="http...></a >.  You can find those codes on Photobucket and other photo sharing places like that.

When you've found your picture that you want in your siggy, copy and paste it into the signature box.  Scroll down and click update.  After you post something, the changes should appear.

If you want to center you signature put < center > before it [[without the spaces]].

Do you need help with the avatars, too?
