As in, make it so that nobody can post on it? I have no interest in the feature, and I don't want it cluttering up my profile. So far as I can tell, the only use is for people to PM me without the privacy, which is something I do not want others to be able to do.
Go to your profile, click "customize profile", go down to "Settings and options" "edit options" look down until you see "visitor messaging" and untick the first box. That should do it...I think
