Category for official announcements
These forums, seem like a mess, I think at the very least, official announcements should be separate from the rest. To help users identify important posts and reduce the clutter.
Great! I think it would also be useful if there is an option to add it to the stream. That way we don't have to dig around the forum for new official announcements. Another suggestion, maybe some tool-tips with labels for the icons for profile, alerts, and settings would be useful for new time users.
