Actually I have never received a response from those folks in any form. I have tried to get in touch with them on the forums, IRC, and email. It's like a ghost town. I have heard from others that they are not so open to people "fixing" things in their database.
I wouldn't mind it though. At the very least it would be nice to have access to the information that would allow me to add the missing pieces to my own database. I have had good luck with you and Cavedude though.
