We're currently in the process of improving the CVP web site. This includes using single sign-in sessions, ability to use OpenID to sign-in, and an improved comment and rating system. This work takes time, so please be patient. The indexing and current commenting/rating system will be in various states of change over the next several weeks. We will try to keep things usable, but just keep in mind that all this work is done in our spare time.
Thank you for your patience. I think the improvements that Fergus is making will be well worth the wait! --D. Howe, 3/18/2012
