Thanks!
I figured it out... basically, block them from viewing the forum (
vB) and then present this:
(insert code in the "header" template AFTER
<!-- content table -->
$spacer_open Code:
Content visible to verified customers only.
Optionally, you can also edit the default
vB message no permissions message that appears...
I've got 506 users sitting in the waiting confirmation email... with 35-45 registerations daily, needed to put some control on it along with weekly deletions.
