Seems like the emailing of user registrations was not working for a while. Sorry about that. Seems that a lot of spammers were registering using bogus email addresses and then the server would try to send them off via gmail, and they would bounce back, and gmail would then restrict the account for a few hours. Ugh.
That has been taken care of I think. I also weeded out inactive accounts….so if you registered at some point and didn’t do anything other than take the PDFs here, well, chances are your account was deleted.
Happy New Year!
