He is a friendly,mature and active guy that is fun to play with, however because of this whole leaving nonsense (which I do not understand or know what it is about) I think it is unlikely that you will become admin again.
I will base my decision of what I know about you, and from what I know you are a good fun guy to play with, therefore you have my
support

I do think however, you need to give everyone a good reason to take you in again (from what I understand) because a simple apology will not do for some, abandoning this community for another because you could get a rank there would mean to some that this community is not your priority and you could just leave for some other community that you believe to be more important. You could have also presented yourself a bit better, some of the spelling is out etc. (I am not one of those grammar nazis but to me in this app it just looks like you rushed your app eg, ' server iand i active' I know you put down your english as OK but to me this looks like it was more rushing than actually making these mistakes because of your language limitations.)
This is one hell of a long post!
