Hi, is it okay/possible to disable EE2 on the fly? Ie. when people are already using it on the server. Someone just invented a machine that turns solar power into blocks of diamonds or basically anything else too. I kind of wish we didn't have that. Stop server, edit modloader.cfg, restart server = win or lose? Also could I just disable some of the items in it? Probably need some plugin for that?
