Whoa, just topic headings but not the actual thread discussions?? A bit extreme don't ya think?
Also, that will effectively nuke all of our content from google's database. Their spiderbot won't be able to access the data either as it can't "login" with a user account and can only index content visible to the public.
It would be ok to have a few "premium" member access only boards, that are off limits. Trading grounds made a perfect candidate but what else would be a good fit?
