Thanks Simo. That helped once I added the Forum Activity Panel as it's not enabled by default.
The one thing that we have with our current host is the ability to link to all the New Posts that have happened since a user last logged in. It's basically a link to a url;
<div style="text-align:center;"><a href="/forum_threads/unread">Click here to find all the unread posts</a></div>
If any User clicks that, then they see a list of Forum Threads that have New Posts in them that they've not read since their last visit which is damn handy. Ideally we'd like to create/use something like that.
Just noticed as well that there's no Preview button, only Post Message.
