I know it isn't even Thanksgiving yet, but I had some moments of thought about next term today.

I'd like to have every person in both of my classes next term (cyberlaw and communications law) posting reactions to the reading/answers to questions/suggested new questions online in some comfortable wiki-place.  This worked well in my seminar last year, and it was great to see the students reacting to things their classmates posted.  (I've said this before -- I knew the class was going well when they started arranging for cyberlaw-seminar drinks after school using the wiki.)  The Paul Romer online problem-set approach doesn't fit law school perfectly, but the lecturing-plus-exam approach isn't the best either. 

So, not for the first or last time, here's a request:  if you've got suggestions for online tools or techniques that have worked well for you, as a student or teacher, please let me know.
