in the zone table.
Code:
INSERT INTO zone VALUES ('gmhome','cshome','GM Home',100,0,0,0,100);
This means when you "/zone gmhome" it will zone you into the cshome zone file (looks like the same zone) but with the name gmhome in /w all list and when you zone in it says "You entered GM Home". it is also restricted to status 100+ people (last 100)
