Send your first message

You're signed in. The sidebar shows your workspaces and (if your tenant has any) some default rooms. Time to create your own.

1. Make a room#

Press N (or click the + next to your workspace name). The New room dialog opens:

Mode: pick Group for a room you'll add others to. (Direct message and Incognito have their own tutorials.)
Name: anything — try playground.
Topic (optional): a one-liner shown in the chat header.

Click Create. The room opens in the middle column.

2. Type and send#

The composer is at the bottom. Type "hello, ScaiWave" and press Enter. Your message appears in the timeline, attributed to you, with a timestamp.

A few things you can do right away:

Newline: Shift+Enter.
Mention a member: @ opens an autocomplete; pick a name.
Emoji: type :smile: and it'll resolve to 😄 on send. Or pick from the picker (😀 button next to the composer).
Slash commands: type / to see what's available. (More in Master slash commands.)
Markdown: **bold**, *italic*, `code`, code fences, tables, footnotes. All render in the bubble.

3. Bring someone in#

Click the members icon in the chat header (or the room name itself, then Members tab) → + Invite. Search by name; the person appears as invited. When they accept, they show up as joined.

If you want a public room that anyone in your tenant can discover, edit the room's settings → Discoverability: Public. It'll appear in the directory at Browse → All rooms.

4. React, edit, redact#

Hover any message:

Smiley button → react with an emoji. Reactions are visible to everyone.
Pencil button (on your own message) → edit. The original is preserved in history; edits are marked.
Trash button (your own messages, or others if you have power_level >= 50) → redact. The body is replaced with [redacted]; the event itself remains in the timeline for moderation history.

5. Find what you said#

Top of the sidebar has a search box (or hit Cmd/Ctrl+K). Type a phrase from your message — within ~2 seconds of sending, hits include the new message. See Concepts: Search for what's indexed.
