Apologies, but the site was spammed over the weekend and nearly 2,000 fake accounts were added.
I've gone through and manually deleted the accounts I think are fake but I may have accidentally nuked some of the real ones - sorry...
PLEASE re-register if that is the case noting that there is now one of those horrible Captcha things and that I have implemented a layer of anti-spam software to try and haul-up those offering me unusual libations and dubious treatments.
Oh no! Thanks and well done for sorting, @maidenbartok.
Just to clarify to everyone, this issue has only impacted the forum - the main site is completely separate and unaffected. These kinds of spam attacks are fairly common with WordPress sites like the forum but it sounds like David has put in some good security measures to prevent any further issues.
