I thought I already explained this to you. Also, why did you post it in Server Corps? You've been around long enough to know where to post.
*Sigh* Anyways *Copies and pastes*
For Signatures:
1) Go to
My Files and upload the picture, be sure to refresh your list after you upload it. You don't have to do this if the picture you want is on a website.
2) Go to
Profile again, in the 'Signature:' box insert the link for the picture there. However, you have to put the link in-between these: [img]Link goes here[/img.]. In order to have shown you this I had put the full stop in the last 'img' thing so take it out when you do it.
However, the max is 300x125 Also, the size limit is 20Kb. You can read more about the rules on Sigs
here.
