Just a suggestion from an old time forum user.
I just checked quickly and I think none of the sections of the forum are private (members only). Its not that I want to post nudes or anything, but I wouldn't mine an off-topic section to be members only so that its not as searchable on google. I know at least I would be more comfortable in an off topic/private format to blab about whatever.
That way I can tell headshot the specific address I saw his mom at last night and dont have to worry about other people seeing it.
