the post linked below says how to display the number of unread messages.

But I would prefer the idea @acaps2007 has proposed, that’s the “notification” item and the mouse over effect, since in a buddypress community, we would have
1. private messages
2. friend requests
3. group requests
4. group invites
5. mentions

Although the last one is not included in the default bp notification count, combining the previous four in one place would still help a lot.
