Whats a signature?

Hi id just like to know whats a signature. Whats it? When i tried to do one on my profile and i posted a reply all would come was "{GTB} birra[i][embed-flash(width,height)]"

Like for some people after they post replies or topics a picture with their name comes up at the bottom? How do you do that?

For a siggy, you need to click on your profile button, then the signature link.

If you're lazy, you can click here: Siggys

There you need to add a link to your signature image in between the "[img][/img]" codes.

Code:

For example, my signature code is:
[img]http://i292.photobucket.com/albums/mm24/urmshimself/urms.png[/img]

Then press save and it should work
