He was a member of Pelletheads, then went to another site and became a moderator, then signed up for this site. He along with several others were deleted. I made the post you are referring to and advised any who were deleted to contact me and we would get them set back up! Only one has choose to do so, so I am assuming the others don't want to be part of the site, or have not been back in so long they don't know/care. The only section a guest cant view on this site is Competition section, and yes, guests can't post. They have never been able to.
Either way it cleans up the site. I would prefer to have 100 Members who contribute, then 100,000 that are just members in name only. We are never going to monetize this site, so large numbers of Members mean nothing to me. Content is what drive a site like this! And the only way you get content is with contributing Members.
If I had it to do over again, it would have been like Old School Alcoholic's Anonymous, you would have needed a sponsor to become a Member!
