Ok I am confused! I read this tracker item and its related links but I still don't get it. Everytime I come onto moodle I get a long list of messages from people, most of which are not messages but are forum posts.I have unticked all options to have forum post notification in my edit messaging screen because I don't want to see them there -but they are still appearing (and confusing me, basically, because I only want IMs to appear not forum posts)
I use those settings and I no longer receive messages posted to my subsribed forums in the pop-up window.
Currently forum notifications are messages. the options (email, jabber, popup) are just how you would like to be notified of them.
Its seems to be more or less unanimous that having forum post notifications counted as messages when you have email notifications set up is a bad idea. I'm working to re-add the ability to get email notifications without having forum post notifications appearing amongst your messages.
Joseph - that is how I have mine set up too, but reading Andrew's post here I understand it better - looking forward to the improvement
May I add it would all look more clear if you changed the Online and Not online labels to When online and When not online. Or even more clear : When I'm online and When I'm not online.
Took me some time to figure this out.
