Changing Region to State on Add Listing Page

Hi,

Now that I have a looking background regarding Firebug and CSS I would like to make a few changes on the Add listing form (and others) but I was af”raid that changing the public side name of such fields as “listing title” and listing description”, etc may cause problems in internal programming. Or are these just titles representing internal names?

Also, if you could please remind me of the area in the plugin to change the names of Region and Zip code? I did this before the upgrade along with the field ‘timing’ but I can’t remember how that was done.

Thanks,
