Cost
Most online adoption registries will have some type of a fee associated. Some will charge you up front, right at the start, and others will allow you to register and search for free and only pay when you are ready to view the results that match your search criteria. For example, if there is nobody in the system currently that matches your search criteria, you will likely not want to pay to view the results. However, if you have a good number of matches, then you may wish to pay to view the results. It should be up to you, you shouldn't have to pay until there is something of value in it for you.
Help and Support
If you pay for an adoption registry service and are not happy with it, you should have a place to register a complaint. Help and support is very basic and important thing to consider before choosing any online adoption registry. Using an online adoption registry that processes payments through PayPal will also help in the case that things are not to your satisfaction. PayPal offers several options to mediate with a service provider when you pay using PayPal.
