has anyone replied?
if not, click 'Profile', then on the navbar for the profile (under the main navbar), click 'signature', then put the image you want in your sig by pasting the image url in [noparse]
[/noparse] brackets(using a photobucket/tinypic/etc. image uploader, or just find one on the internet.)
then click "enable signature" and "save settings"
i hope that makes sense, i can do an image tutorial if you need it
