You're more than welcome. In this case, looking up on YouTube actually would have been quick. However, the way I grabbed it was to open the thread in an iOS browser and then press and hold on the video which pops a menu with a copy option for grabbing the link as text. I played a bit with the SAF app but it doesn't appear to have the equivalent functionality. The closest I could get within the app was to select reply and it displays a mangled version of the video's URL.Thank you!
I should have had the wit to look on YouTube and just grab the link from there.
