When you register you will get an email telling you your password and inviting you to log in. Unfortunately unless I have got round to activating the registration you won't be able to do so. I hope this is just an early "teething" problem and that there is some way to delay the email until after the registration is activated, but for now you'll have to try/wait/try/repeat until the account goes live.

No prizes, but here is a small challenge to get you back in the swing of things. It's stolen from Terry Pratchett, but I'm sure he wouldn't mind. Why don't we try posting the solution as comments, one letter at a time. So once you think you know the decrypt post the first letter of the solution. The next person to get it posts the second letter and so on.
