Is there a method of deleting all of your posts.
Is there a method of completely closing your profile out.

Why, what have you done. If there is a reason the authorities may want to see some of your posts, your probably s hit out of luck. If on the other hand you are innocent of any false accusations you will get your day to defend. Should be no worries for the time being. Deleted files are a false comfort in this day and age of computer forensics.

Witness protection program :wink:

Whats done is done man. Can't go back.

so no actual assistance here, perhaps from a moderator?
