You asked for what some of us may have wanted to see in the app;
I look for more detail on all of your main points. Explaining experience or extra maturity you have would be beneficial. Maybe adding what would make you unique on the team.
The weakness section is the next biggest; do you have a time commitments that could prevent you from coming on meep for extended periods of time? Have you ever had trouble breaking rules? Or trouble with other players? Or anything you are worried you may not be good enough at, that could be a weakness as well.
Anyhow; you seem to have good intentions, and seem to be very mature. Despite showing amazing potential, you don’t seem to have as much knowledge of the process as I’d hope (that’s make me think you aren’t familiar with the rules in game either). Also, there are many threads in the application section that go into how to write a good application. You can use those if this is denied or if you need to write an app for some reason.
For now I’m a -1, because of the lack of knowledge in some general situations. But that could easily change to a +1 if you figured this kind of stuff out.
