Globes are tokens. If you want to stay in someone's home and they can't come to yours for whatever reason, then you can offer a Globe. You can then use that Globe for a stay in someone else's home. It's up to the two of us to decide how long the stay is. It can be anything but, typically, it's a week or two. It just makes it much easier to organise one-way exchanges. When you go to make a proposal, if you select either a Non-Reciprocal or Hospitality exchange, you'll see a Globe section, but you'll only see it if both you and the other member accept Globes and if you have a Globe to offer.
