For admins only
You have to be an organisation owner or admin in order to make these changes.
You want to provide your users with "default groups", so they get to know Grape faster? No problem!
Every Grape organisation has 3 default groups to start with: development, general and off-topic. You can rename them, of course. You can even delete one or two of them or create more default groups for your users.
Settings
For this, click on the gear at the top left and go to "Manage members"
Teams View
Click on "Teams" in the middle section next to "Active members". Here you can choose which users are in which groups per default.
All Users
The very first team is always for "all users" with the 3 mentioned default channels pre-set. Click on "Edit" to make changes.
Base channels
In the following view you get to choose the conversations all users will be added to.
Important: You can only select public groups. Inviting all users to private groups, wouldn't make much sense anyway.
Done!
By clicking "update" all changes are made and all users are added to these groups. Users cannot leave these groups, but always have the option to mute them in case it gets to loud in there (see in notification settings).
