New Spam plugin added to Forum.

[richb]

We have activated a new spam plugin. It is aggressive on new users who are submitting their first post. If it sees many links to other sites it will deny the post. We actively review the denied posts. So if this happens be patient, we will approve appropriate posts, Continually submitting the same denied post will not work until we have approved the post. If approved, the users next post will be allowed.
