For group hashtags to work, the group user must follow all its members; otherwise the posts might not federate to the group's server.
### Opting-out and #nobot
The group service respects the `#nobot` tag in users' profiles. When it's detected, the user's posts can't be shared to the group using the `/boost` command, unless they explicitly join.
To prevent individual groups from boosting your posts, use the `/optout` command.
### List of commands
*Note on command arguments:*
@ -165,6 +171,8 @@ For group hashtags to work, the group user must follow all its members; otherwis
- `/ping` - ping the group service to check it's running, it will reply
- `/join` - join the group
- `/leave` - leave the group
- `/optout` - forbid sharing of your posts to the group (no effect for admins and members)
- `/optin` - reverse an opt-out
- `/undo` - undo a boost of your post into the group, e.g. when you triggered it unintentionally. Use in a reply to the boosted post, tagging the group user. You can also un-boost your status when someone else shared it into the group using `/boost`, this works even if you're not a member.
**For admins**
