We've tried to contact all Ci3 users via email to notify them of this change. We're encouraging Ci3 users to consider migrating to the newer CiW platform.
We know some of you will be holding on to Ci3 for certain business/personal reasons/functionality. We are supporting "the rebellion" (think Star Wars) by providing a dedicated Ci3 area on the Sawtooth Software Forum where you can post questions and answers. Sawtooth Software employees may occasionally participate on the site (Darth Vader, AKA Chris King may show up unannounced), but we cannot guarantee that we'll often be there.
