Sorry about that. 2 months ago we have had a lot of spam on the site so I turned off many of the functions until we could keep it all under control. We have managed to keep them out by changing the way we allow people to join the forum - instead of email activation we have to approve their username and email address. One of the other functions was that people previously were posting attachments and all sorts of stuff so we jsut shut it down and if anyone want anything activated or having trouble they would let us know, as in your case.
So I will activate all back for you and if you are having any other troubles just let us know. We want you in and the bad guys out.
