InkPanther: That was not me. :P And clearly somebody has found those stickies, so they're not completely invisible.
A few people finding the Stickies doesn't change the fact that the Stickying of de-listing threads is still a very bad idea anyway.
For every one person who saw the Sticky, there are probably at least 100 more who will never see it, because they have been acclimated automatically to ignore all Sticky threads, since either the stuff in them only has old information that has already been seen by them years ago, or else the Sticky threads contain unimportant & irrelevant stuff which never should have been Stickied in the first place.
So best thing for the customers is for GOG to revert back to their previous policy of
not Stickying de-listing threads.
