BuddyPress.org

This is very helpful, but I would really appreciate one more thing. The nav bar has a link that says “Notifications”. When you get a message or something, it adds a number to the side, for how many notifications you have. For example, if you get one message, it puts the number “1” on the right. When you mouse over it, it shows you the notifications and you can click to go to them. How would I put the same link with mouse over effect on my site? I am very confused. Thank you for the help!!!
