Any body out there using RenWeb? Looking for some good or bad feedback.

My school is thinking of going with RenWeb. Currently we are using Redikers Admin plus and it isn't so great. Have you ever used RenWeb?

Above is a link to one question: What do you like/dislike about RenWeb.

Thank you for your time.
