Create Guild without Guildmaster ;)

It's possible to create a guild without guildmaster.
So here are the steps.

1. Create a new Guild.
2. Invite a Friend to your Guild.
3. Rightclick the player/friend at the Guild Window 
4. Remove from Guild and let the popup open
5. Now create a macro: 

/gmaster "XYZ"
/click StaticPopup1Button1

6. The Guildmaster will be removed and the guild will exist forever in the database even when you leave it
