^ Well, I see your point, but at the same time I don't really think it's that inconvenient to have to re-register if, for example, in the suggestion by DeviantAngel. If a user has not logged into his/her account in 2 years, which leads to your account being deleted, it's obvious that you don't need FTalk. And it only takes a minute or 2 to re-register. No big deal, I think. And if your account has simply "expired", but is able to be renewed, I don't think that would be too big of a deal either.

I agree with the suggestion of DeviantAngel. 7-9 months, you account expires (but is renewable), and after 2 years your account is deleted.
