Let me attempt to clarify.
Copying text from any website has never been allowed. We've had this guideline in place for many many years (since inception, really).
You are allowed to link to other websites as long as the context falls within the rest of our Community Guidelines (example: no advertising, promotion, selling, etc).
You are certainly allowed to link to information, such as what John Heald posts on his blog. I understand that it is difficult to link to individual Facebook posts. However, that is a Facebook functionality issue which I won't apologize for
We do allow links to Facebook pages, as long as they meet our current guidelines. The information posted about Facebook GROUPS on our ROLL CALLS is specific to members who are creating Facebook groups for our ROLL CALLS. That isn't allowed.
Hope this helps,
