I want this server to have the Not Enough Items Mod plz :)
The server does support the NotEnoughItems mod, However it's impossible for it to be 'added to the server' as it's a client mod. The server cannot modify your client/add mods to your client, You have to install them yourself.
If you install NEI yourself, You can use the patch I created: http://forums.kaise123.com/index.php/topic,905.0.html (http://forums.kaise123.com/index.php/topic,905.0.html)
