Vanilla-not cheap...and why pay for something that can be delivered in Moodle-not clear to me-sorry.
Categorizing, classifying posts...threads...info for practice is nice....new...and timely....Tim's post links with this. I think with a bit of code-fiddle....could fill a gap-how that is manifest needs a team...teachers, coders, academics and Joe Bloggs-user....there is time between now and August.
So, planning needs to take place.
Looking forward to the next MOOC-aiming to participate...looking forward to the next UK MOOT too....p'haps such issues might be discussed at that meet....see you there!
