My question is really to Malte and the AISEC guys to see if they happen to have already done this but I figured I'd ask on the board incase someone else had done it or someone else wants to.
But yes Don, we definitely want to replace simple survey with this package and Don your priorities are good ones.
I would encourage anyone who wants to do anything interesting with survey/polls/assessments/testing to use the contrib survey. Such people should also be aware that there is an active group continueing to develop survey for both dotLRN and nondotLRN uses and that development priorities are being driven by specific client needs. Participation is more then welcome.
There is extensive documentation on the "assessment" project here.
