You're not technically full moderators. But all Club Members do now have one Moderator privilege: The ability to approve the first posts made by new forum users in the public sections.
When a non-member first joins the forum, their first three posts will require approval by any Moderator or Club-Member. After those three approvals, they can post freely.
I've also installed reCAPTCHA and Akismet. Those strategies combined (fingers crossed) seem to have put a stop to all spam so far.
