Hi, I believe I have come to the right place for suggestions
There have been a few occasions on this site where I would have found it useful for mass messaging, that is PM's between a group of more than 2 people.
Where I find this could be useful is when discussions are taking place in a thread which begins to go off topic, and a Moderator steps in to direct the thread back on topic and reminding posters as usual they are free to continue discussing the off topic issue by PM. Yet the off topic issue is being discussed by several people but it is not really serious enough to start a new thread.
I'm perfectly open to the idea this may create exclusive sub-forums so I think an upper limit to how many people can be included in such messages (another forum I am a member of has a maximum of 10).
Cheers

P.S.
I have of course, before I made this suggestion, already poked around the mail settings to see if there was such a feature already in existence which I hadn't spotted but it is possible I am a complete noob and this already does exist but I haven't found out how (I have made suggestions for features that already exist, elsewhere on the web, before). In which case, kindly notify me and save me embarrassment by deleting the thread.
