Switch to XenForo Forum Software
It simply just works better and is a bunch more applicable as far as addons and other features go.
Tagging is still such a pain I get ghost characters every time I tag someone with an underscore. Xenforo can also allow users to have live chat and many other advantages using addons that are updated frequently. Alerts and notifications actually work with ease. Permissions are probably a lot more customization than the current setup. Ranks are easily display and a whole lot more. Customization name colors in posts. You actually get a real profile. etc etc.
