Sorry if I say this, but that doesn't change anything. I'd recommend editing your app before the SD Manager takes a look at it, there was probably a reason you weren't responded to yet by him.
First of. Yes this is a -1 and only leaning to a Neutral if you fixed my problems with your app below. I dont intend to upset you with my reply just take it with a grain of salt.
SA is not a leadership position. The only position you have as an SA is to be the Directors Helper by doing sitreps or informing him of on-going operations. Personally I would only count playing SA as gathering experience from other Directors but just simply said SA is just the Directors little Slave. I'll be fine with the HoS part, fair job if you can master it.
Also this does not make me feel like you'd be a Site Director. Following and obeying rules is expected of all SD's so it doesnt make you stand out from others. "Listen, Learn, Teach" does not sound that convincing either, tho learning is always a step ahead.
Talking about the rest of your application, from personal point of view you kept every section quite under detailed (at least the once that require detail), you explained most things from how it works on the server, SD and O5 section are just roughly summoned up together and dont really show too much information about them. I havent seen you stand out in the server so I can only judge you on the application. Would be fair if you wouldn't have seen me either because I mostly play DoEAA.
