Crap name I know, we will rename it suitably if required...
Anyway, what do you guys think?
This is a paid plugin (although only $10) for the the forum that adds a sort of 'unread posts' functionality and a couple of other features. Not sure exactly how well some of it will work with our forum, especially the 'preview' option on some of the longer threads.
Anyway, you can see it in action on the miniBB site (link at bottom of page) you will need to register on there before you see the miniBB option in the top menus. (Where out PM's one is)
