I think there's more to adding another owner than just having an opening...
If PZ is like a business, owners are holders of equal shares of the company, each with a vote on how it is run.
When Teamplayer resigned he would have sold his share to Gigo making him the sole owner.
Gigo is the only one in charge of the shares, and the server now.
You don't let that power go because 'there's an opening.'
What I'm saying is PZ needs a while to find itself before adding more owners.
Also Gamer would need to know what running the server entails.
Probably coding, and a business license.
