I do (or did
lol..) have access. I also find the registry information to be a valued resource as mentioned by others. I also agree that Chucks dedication to building and maintaining the site is awesome, despite computer idiots like me complaining.
When building the site years ago he was allowing access for data. Now I have additional data for cars not entered by me to provide. I guess I was just frustrated in the fact I couldn't figure out a online way to submit it. Then as a last resort I went to use the contact button. Typed a message and was unable to send it do to my lack of computer knowledge. I'm use to typing a message and hitting send. This one asked all kinds of ISP information that I didn't know so I just gave up.
I do think the site is a little cluttered making it difficult to navigate for a first timer or occasional user such as myself.
