Hi Gary, I really appreciate such a nice words!!!!
Concerning the search nothing important have been done yet. Just a plugin to add a dropdown to the actual search, choosing one of the custom fields in the backend... see the example here http://web9.ioptimas.com/
As you may know all of us, the ClassiPress users, we are waiting fot that new version upcoming to keep the job rolling
Your suggestion sounds spectacular and it is a pity I don't have so much free time in order to achieve this
Have you+family+friends the happiest new year possible!
See you on January 2011 for your next project.
