I have sent a new volley of e-mails to Bakalor (who may or may not be done trying to help - haven't heard from him today), to one of the heads of the software company, and to the guy who's been helping us. Hopefully, someone will respond. Someone on their chat board answered my help post and he pretty much confirmed what most of us suspect - that there's something in the permissions page that allows only one post from our old usernames, then disallows further posts. I've sent everyone the link to the permissions page, and this guy's response. But they move verrrrry slowly.
