// Greasemonkey user script - punBB shout blocker
//
// This script disables strong (bold), color, and font tags 
// in user posts on punBB and vb boards.
//
// At some point I should probably break out punBB and vb
// components into separate scripts.
//
// This is also my first greasemonkey script and hence an
// utter hack job.
