Meta is starting to test closed spaces called “members-only worlds” in Horizon Worlds, its social VR experience. The company has begun a limited alpha test to give creators the ability to grow and moderate their own communities. Meta has selected a small group of creators to build and obtain feedback about members-only worlds.

In a blog post, Meta explained that creators can hand-select members and offer them exclusive experiences. During the alpha test, each members-only world can have up to 150 world members and 25 concurrent visitors at any given time. With members-only worlds, creators can launch a dedicated space to do things like host a book club, gather a gaming group, organize a support group or just hang out with friends and family without having to worry about uninvited guests.
