Topic management
Round Robin can help you spread the word about your rotation status by setting the topic for one or more Slack channels.
Enable topic management

You can enable topic management in the create/edit rotation window (or via the web dashboard).
The topic channels selector lets you choose which channels you want to announce to using the topic system. If you do not select any channel, the channel list from the rotation will be used instead (this is the default).
Topic templating
The app uses a default template for the topic. For manual rotations, the topic looks like:
Round Robin says: %USER% is on duty for rotation %NAME% %UNTIL%.
For auto rotations, the default topic instead looks like this:
Round Robin says: %USER% is on duty for rotation %NAME%
If the rotation has a duty group enabled, the template will also have this sentence added at the end:
You can also ask for help using %DUTYHANDLE%.
You can customize the template using the web dashboard. In that case, you can use the replacement tokens to build a topic the way you like. For more details, see the templating and message management sections.
Keep in mind the topic does NOT support Slack markdown.
Clearing the topic
If you disable topic management for a rotation, or delete a rotation with topic management enabled, the app will automatically clear any topics that were eventually set.
This will occur only if the app sets the topic; if someone else modifies the issues in the meantime, the clearing process will not occur to avoid overriding those changes.
