I would have to agree with that. I have seen too many amateur sites try the trial and have their whole site downloaded and all their content put on another web site. Not that it can't happen with a full membership, but at least you got more for it, LOL
Seriously, unless you have ALOT of content to keep them coming back, they just won't. If they join for a trial and go in and see you have a few galleries and a bunch of BS, they just cancel. They are getting smarter
