Spaces

A Space is a named group of channels and people inside one Account; channels hold the messages, and threads hold side-discussions.

Open Explore Spaces from the destination rail, search for the Space by name, and choose Join.

Choose the plus button in the destination rail, name the Space, optionally add an image and members, then choose Create.

Open the Space menu from the rail, then choose Leave Space to remove yourself or Delete Space to remove it for everyone.

A channel is one shared conversation inside a Space; a sub-channel sits under a channel and draws its members from it.

Choose Create channel in the Space you want, name it, pick who can open it, then choose Create.

Open the channel's members list, choose Add member, then add a person by name or email, or bind a workgroup.

Space administration grants four separate things; channel roles are stored per channel; Space roles are name tags that grant nothing.

A Space can be shared with another Account through a collaboration; members of that Account then read, or read and post, in its channels.

Open the actions on the message you want to answer and choose Reply in thread; the replies open in a panel beside the channel.

Threads appear under the channel row in the navigation column and in full on the channel's Threads tab.

Type @ in the composer and pick a name; a resolved mention notifies that person even when the conversation is muted.

Unread counts conversations that need you; Mentions counts the individual mentions inside them. Both are per destination.

Set what a single conversation notifies you about from its row menu, and set the default for everything in Spaces settings.

Open DMs in the destination rail, choose the plus button, pick one person for a direct message or several for a group.

Open the actions on a message and choose Pin message; pinned messages collect on the channel's Pins tab.

Use the plus button in the composer to upload a file or pick one from Drive, or drag files onto the message pane.

Files lists everything in the channel's file store, newest first, with a download control on each file that has one.

A link pasted into a message expands into a card; GitHub, scholarly, media, and Evolve links get purpose-built cards.

Press Ctrl+K or Cmd+K to search everything you can read, or use the channel header's search box for one conversation.

Choose Start call in the channel header, pick your camera and microphone in the pre-join dialog, then join.

A desk is an AI teammate you reach by mentioning it in its own Space; agent work can also be started from a single message.

A Space you expect is missing because you are not a member, it is invite only, your Account lost Spaces access, or a collaboration ended.

The composer is locked because the channel is an announcement channel, it is archived, your access is read only, or a send failed.

Files is on every channel; on a narrow window its name is hidden or the tabs collapse into a menu, and an empty channel reads No files yet.

Check the conversation's own level and mute state, then your account default, then the browser's permission for this site.
