Invite people to join your community one at a time.
Spread the invitations over two weeks
Invite the best people last.
The more invitations you write, the better they become. By the 20th e-mail, your invites should be perfect. This means you need to spread the invites out over a week or two. This gives you time to see what’s working, and perfect your later invites.
So the people you most want in your community, should be the last ones you invite.
