Let me spell it out then:
If you conenct to 69.153.214.246:27930 and after you are conencted, bring down the console, type "login map", that will give you a command level at 2.
That doesn't sound like much, but it will allow you to change maps on the server.
Once you login, type newmap ( map name of your choice with the exception of jump maps) and the map on the server will change.
THis will allow those that want to play a certain map go ahead and change it.
If it's abused, I'll diable the feature.
Is that clear now?
