We have undertaken “The Test” and the results are in!
When you “invite” a participant, and they accept the invite, they will see the entire thread. Further, tagging someone in the thread of a private message does NOT generate an alert for them or bring them into the conversation, it has to be a direct invite and that invite has to be accepted. If you are a participant in the conversation, then tagging will generate an alert, and if the tagging is in a reply to the person tagged then they will get two alerts, for the tag and the reply.
Thanks to all that participated in the test!
Oh wow, discourse blocked me from making a “fourth reply” in this topic, even though one of my three replies has been deleted by me prior to attempting my new “third”!
anyway, here is my “fourth/third reply”:
This experiment does show that the group direct messaging is very functional in discourse, and similar functionality in iNat would be awesome. However, given the much stronger connections between the forum and iNat since the move from google groups (accessible from community menu, process/pathway to keep usernames consistant between the two, etc) I can’t help thinking that perhaps discourse is a better option to hold such conversations in anyway. As soon as the functionality of the iNat direct messaging system becomes limiting, is perhaps the trigger to jump it across to a “group conversation” in the forum.
