I don’t know why I didn’t think of this before but there’s an easier way to copy the link than I described above 
You probably already know this but I’ll post it anyway just in case you don’t.
Instead of clicking the link as I described above just hover the cursor over the link (in this case “Re:Link to a particular POST”) and right click, then from the right click menu select “Copy Link Location” (Firefox) or “Copy Shortcut” (Internet Explorer) and the web address will be copied to the clip-board ready for you to paste where-ever you want it, job done
