editing neighborhood dataI have a nice prototype & workflow for allowing public to edit and add neighborhood boundries. I would like to limit editing to registered zillow users & have 1 or more zillow useres agree with the edits. Then i would make that changed data available to zillow & the public.The problem I have is how to authenticate users against zillow.com rather than requiring people to register on my site & provide information they have already provided you. is there any way to do this where I can just ask if the creditials are valid & if so link to the user profile?January 22 2008 - US00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
