jesus,
whoever is in charge of this board why don't you just parse user posts and sigs for "carrots" (
) then replace them with the appropriate html char code
this way they will show up as text rather than become interpreted by the browser.
this way you don't need to block words like 'b-o-d-y', etc
anyway...
the website above would be
http://www.b-odyforlife.com (minus the "-")
hope it helps
