MyBB Community Forums

Okay. So i'm new to mybb.
My friend made a forum and left it to me to handle.
So i got this plugin in which it limits user's sigs to a specific size.
And i'm trying to find out how to edit the template and make something like this come out and warn the user about the limits in the "Change signature panel".
P.S. The screen shot is from another forum i'm active in,




Thanks.

Have you tried the plugin author's release thread for support? I'm not sure how you would go about with a "warning" message unfortunately
