Want your friends to be GM but you don't know how??
Well it's quite simple really all you have to do is follow these steps.
Step 1: Open up your MySQL
Step 2: Then Open your Databas
Step 3: Find "Accounts" it could be in Logon but it depends what Server you have
Step 4: In the fifth colomn of your friends account named "gm" change the ammount to one of these:
az: is Admin.
a: has all the powers of az exept admin.
3: is a High Rank GM with less powers than a and az.
2: still a powerful GM but modify in game things.
1: a GM none the less but with limited powers.
Now save and restart your server and your friends are GM's
