in our community, age matters little. most branches have full members older than you. it makes me smile to think that they got into mopeding around my age and stuck with it...no matter what. rally age range is great (mid teens to mid 60s).
as far as increasing email responses: i would change your photo. there is enough random showings at rallies already :) you may be a great guy, but i personally would be leary writing you back with that photo.
also i am not sure that people check email as much as the forums. i have sent emails and not gotten responses for weeks before.
