I've encountered the following issue. I thought maybe I could use a private discussion to draft a new discussion, so I added only myself as a recipient (thinking I could then remove myself as a recipient in order to publish the thread). However, when editing recipients to remove myself (the only recipient), the interface changes so it appears that I've been removed, but when I reload the page, I see that I am still a recipient and the message is still private. I suppose this could be in the design of the plugin – once private, always private – still worth mentioning.
Have I told you lately … thank you for the time you've given to extending Flarum! ??
