Kudos to The Jockey Club for a site that is user-friendly and well-planned. I've used Interactive Registration the last few years, and it just keeps improving. The main page includes a useful overview of the registration process, and helpful information (such as tips on photographing the foals and describing body markings and colors). But the experience just kept improving. The GUI for denoting face and body markings was not clunky like might be expected; instead, it was a nice graphic with easy-to-use controls. The photo upload was a snap. The records were set up to require the least amount of typing necessary (one click makes the "owner" information the same as "breeder," for example, instead of rekeying names, addresses, email addresses, phone numbers). And each step along the way, I saw a note letting me know what step I was working on and how many steps remained. When I was finished, I received a nice report summarizing the information I'd provided, to keep in my records.
