Fred's account has been changed and now he is locked out of the Forum and cannot post....
I asked him twice via email if he still has had problems - no reply. I tried to sort it Saturday afternoon already.
And yes, it was my fault, as I'd messed around with "membergroups", sorry sorry sorry.

Btw, what exactly has been "changed" in his account? I can see no difference.
P.S.: Tell him to try again! I changed something in the ban list, hope it helps.
