As I noticed, a lot of worlds made not only by one creator, but with different kind of support of other players. So to be fair this ppl should be shown in world profile in game and on site.
So I suggest:
  • to make ablity for world creators to provide user IDs (usr_???) of co-authors in scene descriptor or using API.
  • to show co-authors in world profile not just as list of nicknames, but as scrollabe list under the instances list (may be folded by default): the uploader first and the other provided after.
  • to show worlds in co-authors menu, so co-authors can go to that worlds and drop portals when it's not in public.
  • to show published worlds in co-authors profiles, the same way currently published world shown in author profile.
