You know what? I think the MDP Team is so understaffed and its members are so overworked they hardly can find the time to respond to questions here in the forums. There are times when I did get a response within a reasonable amount of time, but there are others when there's no response at all.
I wish the team's management will soon recognize the importance of external developers to them and staff the team adequately for external developer support. Facebook really is beating MySpace in this area as well.
