[Feature Request] Notifications
This is a major part of any forum, and right now it's a bit hard to keep track of threads that I reply to. This is mitigated slightly by the "Recent Posts" section in the user profile page, but there's no way to view **all** of my posts, or my likes (#129).

Notifications doesn't have to mean emails (although that would be nice), it could just mean a little bell or something in the top right corner by the current user profile menu that shows a list of (maybe most recent 10) recent mentions or replies. Then, a little link with "View all" could be written that will bring the user to a list of all the mentions (lazy loaded or paginated) and notifications.

I think another little addon to this could simply be a list of posts the user is mentioned in or a part of, with "New activity/reply" text and highlighting applied to posts where the user has been replied to or there have been new posts.
