All very good ideas. I'm definitely onboard with these. I especially like the idea of PMing the needn't guy when you get the box as opposed to sheet you've had it for the week.A week is not too bad but yes it will take time. If you ask for the next address when you receive the box, it should give enough time for the next member to respond. If not, email, if nothing after a week skip
I would however not add anyone once it's launched otherwise the last person could wait a year and a half...
