Hi Judi,
The easiest way is to do a copy paste of the back link.
The Ctrl c Ctrl v is the way I do it.
Just highlight the url # link at the top of the page ( top left) it will turn blue. Then hold the Ctrl & c keys at the same time.
Go to where you wish to post it and hit the Ctrl v keys at the same time.
Your clickable link will be there.
Let me know if it works:~)
hugs,
Angela
