A member's ability to join a space is determined by its access type, which is defined when the space is first created.
By default, a space's access type is set to Network, which means that all members of the network may join the space without being invited.
If a space's access type is set to Private, you need to invite a network member before they can join the space.
If access type is set to Open, users are required to request permission before they can be given access to a space.
As a new user, we recommend that you set the access type for your initial spaces as Network. This ensures that anyone can view and join the space. When you're more familiar with how Zillable works, you can then set up Private and/or Open spaces.
