Best vBulletin Forum Plugins 2013

4. AdminCP Firewall
(http://www.vbulletin.org/forum/showthread.php?t=296383)

This plugin won’t have any impact on the appearance of your forum, nor your profits. But it’s still one that’s worth having in the background. Just like any other websites, forums are frequently attacked by hackers, automated scripts, and other online threats.
The plugin will enable a number of security features such as: email alerts when certain events take place, IP checking for admins, user blocking, failed admin login attempts, and more.
