BuddyPress Activate Account Reminder

Activating your account is a bit of an issue on my BuddyPress site. Since I know some of the people who dont activate their account personally, I just use
http://wordpress.org/plugins/unconfirmed/
to activate it for them, but I do not know a majority of the people and want them to activate their accounts.

My theme doesnt have any banner or similar feature to tell the user that their account needs to be activated when it's not, im guessing that this is more of a feature that would be brought about by a plugin.

Any suggestions?
