For simplicity and ease of maintenance, we recommend that you point your participants to that group page. Additional links can be added by the Team in the "Tools" page of the Group if needed.

 All GitHub repositories used by the group must indicate so, using the [`w3c.json` file](https://w3c.github.io/w3c.json.html) in those repositories. If you do not use the GitHub 'w3c' organization, make sure the Team associates your GitHub organization in the 'Version Control' entry of the Tools page (Team may modify those entries using the [admin](https://w3.org/admin) interface) and the tooling will associate *by default* all of the repositories in your GitHub organization to your group.
 
 Make sure the license and code of conduct files are there (Team, you may use the [repository manager](https://labs.w3.org/repo-manager/) to create those).

 To help W3C participants navigate through the various groups, Chairs and Team Contacts must use the W3C Calendar system rather than using separate tools. By default, recurring meetings must be 'Tentative', confirming only meetings that will actually happen or cancelling them otherwise. For TPAC meetings, the events Team will create specific calendar entries. Each meeting should point to where the agenda and minutes did or will appear.

 ## 6. Agenda {#agenda}
 
 To allow the broadest participation in setting meeting agendas, we recommend opening a GitHub issue in your administrivia repository, with a label "**`agenda`**", one issue per meeting. There is at least one issue opened at all time for the next future meeting. You may use a GitHub template to facilitate the creation of such agenda issue.
 
-Encourage participants to comment on the issue in order to add agenda items. Your participants may also add a label "**`agenda+`**" on any issue in technical specifications. If so, Chairs should monitor the [agenda board](/PM/Groups/agendas.html) to catch those (and remove the label once if the issue got covered in a meeting).
