Bacon - it looks like your server path to gas folder is wrong. It needs to be the complete path and not a relative path like /var/www/html/forums/gas/
If I recall correctly, GAS makes a good guess next to the setting itself to try and help you.
cmiller - not really. Once again, I designed this to be seamless and to integrate with the forums. If you want a seperate system and/or file... try vbarticles
