Teaching with Moodle

Hi Tom
Excuse me for the delay.
In fact we find useful setup catogories as groups. 3ºB for example.
Then we have all the courses of this group in this categorie (Math, Philo...)
The point is that categories don't have forums, as main page and courses has.
Well, at the beginig we planned to add a course called 3ºB Main (or something) to be displayed in "social format" at the top of all course list and "force all suscription" enabled on it "news forum", to post there every issues group related.
In fact, later we discarded this all.
The forums inside each course do the job quite well. Each course have their own News forum that "force all" and email every post to every one... there is no way to not be "in touch".
I hope my english are enough to explain myself.
Best regards.
