Unfortunately we can’t even pin topics for our own viewing using the shortcut “shift”+“p” that is supposed to work. Best work around I’ve come up with is bookmarking the thread then going back to it when/if necessary using the keyboard shortcut “g” then “b”. I don’t recall seeing any response to questions asked when the new forum went live about restoring stickies from the old forum that were lost or how to set up new ones.
I realize my suggestion is just a bandage and not a cure. I wish I had a solution.
