Hello! I'm trying to find an easy way to update my Gmail contacts. I got the G1, so I migrated all my contacts to the Gmail system, which means I have a lot now. I am hoping somewhere out there is a way to blast out a form "please update your contact information" email and have it automatically update in my Gmail Contacts. Heck, even some sort of sync with LinkedIn or Outlook would work, since I can do mass updates on those. Anyone have any ideas? And if there isn't anything in existence like this yet, where should I go to post a feature request that it will get seen by the right people in the dev team?

Thunderbird + Zindus add-on?
