Ahh. Thanks, however this seems problematic, because when I disown a collection, I can't tell if another user has contributed to the collection, and so can't tell if I am about to delete the collection without wanting to. This just led me to delete the collection Cannes 2017 Official Selection, for example, when all I wanted to do was disown it. This means that before disowning a collection, I have to go to the moderation page and check who has contributed, if I want to avoid this problem, which seems unnecessarily complicated. It also means that it is currently impossible to disown public collections that have only one contributor. I can understand the idea that you may want to discourage users from starting public collections that are only of interest to them but don't wish to moderate, but I tend to think that the issue is more complex. For instance, people may be interested in the Cannes 2017 Official Selection, but can't be bothered starting the collection themselves or even contributing to it. But if one user decides to take that responsibility and be the one who starts those collections, eventually they end up with a massive list of collections that become difficult to scroll through. An indicator of whether an action will in fact delete the collection seems necessary, and the option to disown a public collection with only one contributor would also be beneficial.
