This is the harsh reality of a Volunteer based support system. For me personally, things were so much different back when I first got Volunteer as a Sophomore in high-school. At that time it seemed as if I had no other obligations but to spend my time on xat; however, this is not the case for the majority of the Volunteer team right now.
Brandon is right. We can't lower expectations in order to meet quotas. If it were up to me there would be a few more users on the team that should have been added awhile ago, but have not due to conflicts that have come up in the past.
