Yea, it's because the config.php file is read before those variables take place. I would ask Kirby, he might have an answer for you. :)

How about making this a plugin? ;)
If you do, variables in question might start workin'. ;)

I'd make some turn on/off option in vbulletin options, with a couple of permissions or something. :)

Oh man great news.. how many minutes i hav to wait? hehe plz make it quick.. either liviwire or Psionic Vision :)

I believe LiveWire can do it on his own :)

Waiting for this plugin :)
