How do I do this? I followed this code here - http://fmdesign.forumotion.com/t1030-display-a-preview-of-groups-on-hover - but it doesn't seem to work. My forum version is ModernBB. If anybody needs my forum link, just ask. Thanks.
Also, I already have this all ticked on:
Note : For this plugin to work you must have the following option enabled.
Admin Panel > General > Messages > Configuration and enable the options entitled "Allow username tag" and "Activate the preview of profiles on the tag usernames."
