I thought the same thing. I tried establishing an email address for each team member, that either forwarded to their email of choice, or a new mailbox if they desired @projectfanout.com
Most team members were real eager to sign up and make huge promises, while a few never even would get back to me on their email preferrences for how the team could contact them.
In the end, about 4 people out of 17 seemed to want to work.
