You can't, the forum administrator installs it. I'm not sure if or when that will happen.
It would be a nice feature but it may have security/stability implications, sometimes when you install new features it breaks something else.

We Admins can't touch the code, and our corporate code guy is rightly extremely conservative about what vB mods he will even consider.
To get him to even consider a mod, we would have to show him at least two vB forums
of similar size to AT that have successfully implemented said code.
So, Blue Blazer regulars, your task lays before you!
