Fleets weren’t long for this world, but Twitter’s product teams aren’t slowing down on bringing new stuff to Spaces, the company’s own take on audio rooms. Twitter introduced Spaces in a limited test last year, expanding the Clubhouse copycat feature more broadly to anyone with at least 600 followers in May.

Now, Twitter is giving Space hosts the ability to add two co-hosts, who they can rope in through an invite system. Spaces will allow one main host, two additional co-hosts and up to ten speakers. Additional co-hosts will make the task of moderation much more manageable, as they’ll be able to vet speaker requests, tap speakers and give anyone in the Space the boot.

With Fleets out of the picture, Twitter’s Spaces are the only feature for now that lives above the main feed in the Twitter app. That virtual real estate, which has echoes of Instagram’s Stories, draws the eye to anything that a social network wants its users to check out first. Twitter also began rolling out a dedicated tab to make it easier to discover Spaces, surfacing live audio rooms in real time in a central location.

A number of major apps spliced live audio chat rooms into their platforms in light of Clubhouse’s breakout run. In June, Spotify launched Greenroom, a standalone app that allows people to create 1,000-person voice events. Naturally, Facebook also launched its own spin on live audio rooms (called Live Audio Rooms) in June. Discord, already a leader in voice-based chat, added its own Clubhouse-like event channels in March. Twitter followed the same trend with Spaces, but unlike with Fleets, it looks like the company plans to continue supporting the relatively new feature.
