My login doesn't work

That is entirely possible. If you're having trouble and swear that you're typing in your login exactly as you remember it from the old site, then the problem may not be you. Do to the new requirements for formatting usernames, some usernames had to be changed. Your old one may not work anymore. There were only a couple of cases where this happened. One of those cases might be you. Get in touch with me, tell me your username, and I'll have a look at it.
