I was talking w/an English teacher last week about Etherpad and did a demo w/my yearbook kids. Great tool, but going away, right?
Fortunately, I put a call out for help to my Twitter peeps and got a number of responses w/alternatives:
Also told about a Wikipedia article w/more options: http://en.wikipedia.org/wiki/EtherPad#Clones @ptruchon send me the Wikipedia article mentioned above, but it has changed (not for the better) since sending it. He suggests this substitute: http://doc.etherpad.org/etherpadsites.
Gotta love Twitter!
More to add? Lesson ideas for using it?
