Frozen, bud, seriously: change it.
While I really do like the neat hack that it is, after you post to ANY thread, the bad code in your hack is causing posting errors.
After you post in a thread, no one else can post in that thread since the post button calls up something in your custom title script that doesn't exist on the server (i.e. a CGI-BIN call).
Namely, "http://forums.qj.net/cgi-bin/example.cgi" which doesn't exist.
If you're going to copy and paste code you find on the net like that, at least customize it to work well with vBulletin and PHP.
