Well, I mean, that is the reason. I would really like to have the experience of being an Admin on a server (other than my own :P)
I think it would be enjoyable and I would be able to help you and the crew out.
I was never able to have a public server of my own because I am using a laptop, meaning I can't portforward, and so this would kinda be like it.
Not really, but kinda.
So, in short, it would allow me to have fun on a server helping out and have an experience I have wanted but never really got (sorta).
