At the time of this feedback, group-shared solutions all have "Created By: —".
Solutions can still be uploaded and downloaded. Downloaded solutions show the same "Created By: —", however.
Shared solutions can still be deleted. Another player's still cannot be deleted, which is correct.
The "Show only my solutions" checkbox, when checked, results in no solutions being shown under "Shared Solutions".
As perhaps a separate issue, http://fold.it/portal/players and all associated links show an empty list of players. (So soloist hall of shame, players with pictures, and so on are all empty.) Opening a separate feedback on this issue.
