How can I put my STCC license image in my signature? I've seen many people here that have them, but I just can't find a way to do it.

[stcc]your_username[/stcc <-- add the close blanket by urself

Also [stcc ]mini/your_lfsw_name[ /stcc]

You can get more information on the tags by looking up your licence here: http://www.simtouringcarcup.com/lookup.php

Great! Thanks!
