Goods exchange
Flying between Sweden and LA? Offer some luggage space. Missing something from home? Ask. It's a favor between Swedes, so nobody charges for it.
Invite friends
Add the email of a Swede you know in LA. Use the address of their Google account. You are vouching for them, so only invite people you'd trust with a bag of Marabou.
Adding someone lets them in. To tell them, tap Email invite next to their name. It opens a ready message in your own mail app.
