It's being worked on with very little volunteer time available currently.
In a nutshell our host turned off the emailing part of it (to receive and click an activation link), because we're on an old version of PHPBB. We're on an old version of PHP simply because we changed web hosts 6 months ago and so we moved it all over intact at it's current version. (they shut us off a couple months later). All the new one will allow is the latest version of PHPBB emailing functions, basically.
In the works is upgrading it, I think. Thanks for your patience.
