If you wanna change a mod via the web panel you can do it by your self
and you don't need to wait for my answer anymore ;)
In this example i use the mod True Combat Elite.
1. Upload your mod folder via ftp to your server and edit the mod.cfg
2. Go to the "Game Monitor" of your server and edit or add the "additional parameters" with +set fs_game tcetest
For other mods
noquarter = +set fs_game nq
etpro = +set fs_game etpro
nitmod = +set fs_game nitmod
Thats all :)
