I am not sure if this one is classified as too hard or not, but I have some suggestions for the Buddy List feature. Those who are added to your profile can have full access to your profile, while those who aren't can't. Such as if you aren't on their friends list they can't see when you are online, your messengers, your links, or any other additional profile features added by the staff. Perhaps the admin can choose what parts of the profile can be seen? This is to help with privacy protection.

As far as I can tell, much of what you're asking for cannot be done without server-side. Either way, the end result would be very unreliable as using noheaders would simply remove all protection.

Your best bet would be to wait for the Suggestions board to re-open.
