I recently installed a new email server for the site and managed to leave a gaping hole in the security which meant that people could relay mail through it if they knew what they were doing.
This was exploited yesterday and a whole load of spam was sent through the server over the last 18 hours or so. This has meant that "normal" site mail has been a bit interrupted during this time.
I have patched the hole and the backlog of TA mail is now going out.
New users - if you haven't received your Welcome email please click the Resend verification email link when you sign in.
Apologies - fortunately I got there before too much damage was done.
I wanted to take this opportunity to also point out a couple of new site features that were added to the site recently - when you view your site leaderboard charts now you are able to see how you compare against your friends on the same board, or other gamers near you on the site.
I've also added default options for the Achievements lists on Game Pages - you can choose whether to show achievements you've won, not won, or all. This is set up in My Settings
And thanks to everyone that has applied for the investigations position, the response has been excellent!
