Is it necessary to publish those own:nnnn tags or make them explicitly public? I found it confused, and distracting. What's the idea to make them publicly?
At this time, all tags seem to be public.
Besides, I would like to know what would happen if I remove those own:nnnn tags?
BGG would forget that you chose those particular images for your collection gallery (the pictures that show up if you click on in your profile) and revert to the Representative Image for each game.
