You have decided to go on a trip with friends. Program: camp, trek ... Congratulations, beautiful adventures ahead!
However, on the logistic side, the distance that separate you from your friends makes your organization tedious (many phone calls, mails etc.).
Why not creating a Zoutch! where you could list everything you need? Who takes the cards, what time you take off etc.
You will then have centralized all the important subjects in one place !
