I swear I had an account yesterday!!!
Well, yes, you did. But that’s on the old site*. You’re on the new site right now. Welcome to Discourse. It’s a new way of looking at the old traditional forum. It’s pretty durned cool, too. However in order to migrate to it, I’ve had to dump everything that came before. This is a fresh start, so to speak.
You’ll need to create a new account, and if we remember who you are (:D), we’ll eventually update your clan access so that you can see the other part of the site. You know the one. 
Sorry to make you go through the whole registration junket again, but this time you should be able to login via Twitter or Facebook - or even Github if you’re so inclined. You can also use Google, or I believe Yahoo (does anyone still use that?) or simply create a local account. How you do it is up to you. See you soon!
*The old site may not be there any more
