Modflag Not Working?

[bubblecon11]

I'm not sure if this is just me, but I am trying to set up a server for Voltz which needs spawn protection from missiles. When I attempt to use the /modflag command, it does not work as suggested in this comment:

use /modflag setregion NAME RADIUS and /modflag set NAME ban_icbm true (it's not listed for some reason)

This has become extremely annoying as I can not launch my server without getting this set up.

Any help would be appreciated.
