Question about "External Site" permissions

It applies to the permissions available to Oauth Clients defined in the platform.  When using OAuth over REST, we allow things like tagging and commenting on external urls, basically storing them in community but they are related to content on another site.

They are altered on individual Oauth clients(.

Thanks Patrick .  In that case, I can't see any way to limit registered users from posting links to external content.  Is that indeed the case?

If you have no Oauth clients in your site, then the permissions will never apply.  If you create an Oauth client for someone to use with REST, then editing it will have a permissions tab to edit as needed(in the scope of the single client)
