Forum posting is by registration-only

[joe]

My honest apologies for doing this, but guest posting was inviting so much spam, this was the only thing I could do for the moment. There's been twenty spam posts an hour recently, and that made the site unusable. There must be some new exploit in the forum software, and made guest posting impossible.

In addition, registration is going to have to be admin-approved until there's some fix for the spam issues.

Again, sorry.
