Hi Dwaine,
It's pretty difficult to avaoid spam in the forum completely. Posting is only possible with login now - but the authers even create an account to post their messages. So we currently manually remove the spam and block the respective users. Theoretically it would be possible to require a confirmation of each new user by us before they can post - but that would mean that new users would have to wait up to one day before being able to post their message. I think that's currently not acceptable. As long as there's not much more spam we'll proceed in the current way.
Cheers,
Peter
