Our radio station is starting a new server and are using the 1.6.4 version of Tek. What we need to know, and forgive me if this is posted elsewhere as we are lacking time, what admin mods will work with TK? We want to use some that we can protect set areas to certain players, area where the main spawn would be so that it cannot be messed with. Second ?? is the /help doesn't seem to work. We get an error message with it. Trying to use the /sethome and /setspawn commands aren't working either. Any help would be appreciated.
