Requesting Writer Permissions
Suggesters and Viewers in a discussion may request Writer permissions (see Participant Roles and Permissions). To request Writer permissions, open the Discussion Menu and select ‘Request Writer Rights’. You will be asked to provide an (optional) reason. If a discussion is private and you do not have at least Viewer rights, you’ll have the option of requesting the role when you attempt to access it.
Only discussion Admins and Owners can approve users’ Writer permission requests. While Writer permission requests are enabled by default, Admins and Owners can choose to turn them off – to do so, open the Discussion Menu, select ‘Discussion Settings’, and uncheck ‘Allow participation requests’.
