Notifications! (Notice the changes to the top bar). There are currently two types: New private message notification and new comment notification. This was a desperately needed feature, sorry for the late release on this one. Click on the icons to read your notifications, and hopefully everyone can figure it out from there
Right now I only have 2 types of notifications: new messages and new comments. In the future I will add notifications for favorites, watches, etc. If anyone has any trouble with this, feel free to contact me.
