Hi
A simple one but I am unable to achieve in my website
How to add a signature to my forum posts?
I tried through URL,  but it just comes up with the url address ?
Any help would be appreciated 
oh yeah I am admin on my website.
Thanks

Check Settings in ACP:  Configuration - Board settings - Profile Options - Allow [img] Code in Signatures.  And you have to insert an image using the editor or bbcode in the signature.
