We have been fighting a war with spammers. We think we have it pretty much licked, but in order to clean up the Forum, we had to mass delete inactive accounts. (Apparently, these creeps sign up hundreds of accounts and then use them over time. Just when you think you have deleted all of the spammer users that have been posting, they start posting with these older accounts.
So, if you have been inactive on the forum for awhile, we may have deleted you too. Sorry about that. Please sign-up again.
