I have a website and I am looking to deliever ads based on on zipcode / radius. On the index page I have a place that I would like to do this (an area for the code) Is admentor pro something I can use for this. Thanks in advanced.

Thanks for your interest - and sorry for my late reply. Anyway: There is no geociding filtering available in the pure admentor so to speak. I.e you can't in the admin interface target a certain campaign for a certain zipcode or so. However - nothing stops you from creating an extra layer above it - in your aspx page you could of course modify the admentor calling code depending on current zipcode - if you are able to receive that. You will need some external geocoding database for that.
