Posting Behaviors
A group's posting behavior (also called posting mode) answers two questions at once:
- Who can send messages?
- Who can read them?
Posting behavior is permanent — locked at group creation and cannot be changed. Choose deliberately. If you pick wrong, the only remedy is a new group with members migrated over.
The three modes
GLYPH supports three posting behaviors. Quick mental model: Normal is a round table, Broadcast is a stage, Submission is a drop box.
Normal
The standard collaborative group. Every member except Observers can post messages, share files, and join huddles. Everyone reads everything.
The vast majority of groups: project channels, team rooms, working groups, general chat, anywhere you want open back-and-forth.
Broadcast
A one-to-many announcement channel. Only Owners, Managers, and workspace Admins can post; everyone else is an Observer who can read but not reply.
Use for:
- Leadership updates.
- Company-wide announcements.
- Status feeds.
- Compliance notices.
Signal-to-noise stays high because regular members can't chime in. The right model for anything you'd otherwise send as a company-wide email blast.
Submission
A many-to-one intake channel. Owners, Managers, and Users can post, but only Owners and Managers can read. Posters can't see each other's submissions.
Use for:
- Tip lines.
- HR or legal intake.
- Security incident reporting.
- Anonymous feedback.
- Suggestion boxes.

Who can do what — at a glance
| Normal | Broadcast | Submission | |
|---|---|---|---|
| Post messages | Owners, Managers, Users | Owners, Managers, workspace Admins | Owners, Managers, Users |
| Read messages | All members | All members | Only Owners and Managers |
| Observer role | — | Read-only attendees | — |
Common confusion: Broadcast vs Submission
These two are easy to mix up. The asymmetry is the key:
- Broadcast is asymmetric on posting: few post, many read.
- Submission is asymmetric on reading: many post, few read.
If you're trying to push information out → Broadcast. If you're trying to collect information in → Submission.
Workspace-level overrides
Workspace Admins (along with group Owners and Managers) can post in Broadcast groups even without holding a group role that would normally allow it. This is the workspace role's authority overriding what the group role alone would permit — see How the Two Role Systems Interact for the broader pattern.
Picking the right one (and not regretting it)
Three minutes spent here saves you the pain of rebuilding a group later.
- Default to Normal. Most groups are collaborative. Pick Normal unless you have a specific reason to gate posting or reading.
- Broadcast is for one-way channels. Use it when the value of the group is preserving signal — and noise from regular members would actively hurt it.
- Submission is rare but specific. Use it when you genuinely need a write-only inbox.
If you're not sure, default to Normal. You can always create a more restrictive sibling group later.
