To be completely honest, the age limit isn't all that bad. Sure, its bad for the mature 10-13 year olds, but its good for the high staff who have to waste their precious time dealing with issues like it.
Despite this, I will still be +1ing this. I think that, if community feedback of an applicant is strong enough, we should grant them the exception that they are allowed to apply and interview. Having 12 year olds in staff is beneficial to the 12 year olds, as they are getting experience for their future and for when they need a job in real life.
tl;dr basically allow certian staff ranks to allow 10-13 year olds to apply if community feedback is good/if they have been prior staff and had no prior issues and they formally resigned. +1
