Three reasons. First, we can provide a better service to you if we know where you are searching from. If we see a lot of people signing up from a certain state, we can concentrate our marketing efforts in that state to make sure there are plenty of Providers listed for you to find. Second, registration protects our Providers from getting spam emails. Listing contact information makes them vulnerable to annoying internet marketing, so registering to see a Provider Listing guarantees only real people see their contact information. Third, we want our Providers to know where people are searching from! The only identifying information we ask from you is your zip code, and this way we can see where the WellCatholic community is flourishing, and where Catholics need to hear more about us.
