Some of you might have noticed that the site was down for most of Saturday, March 21. This was unfortunately due to some unplanned site maintenance. 
We have taken the opportunity to migrate the site to a new hosting provider, which will hopefully resolve some of the major issues with e-mail that new users have been experiencing when attempting to register on the site.
As part of the migration, we unfortunately had to rollback the site to a backup from March 14. If you registered on the site between March 14 – 19th, please register again.
