Sidecar Pro - 4 missing in action sidecar riders email addresses - help needed

I am hoping either the 4 riders themselves or friends of theirs on mychinamoto might see this and be able to notify them that I have tried really hard but unfortunately are unable to send out replies to their requests:


Phill D. from New Zealand
David B. from San Diego with a CJ M1M
Mike from New Jersey
Marc D. from USA with a CJ OHV


They have submitted their requests via the webform at either:

http://www.sidecarpro.com/registration.html
http://www.sidecarpro.com/product_ideas.html
http://www.sidecarpro.com/contact_us.html



however have either not completely filled in their email addresses or there is an error in the email ID as my email replies are bouncing.


If anyone would be able to help it would be much appreciated.


Cheers


Ben
