Well that is what Scottrade told me. Everything is now done electronically. I received all the forms for the C/T's to file a claim from Scottrade. Scottrade forwarded them to me per an outside request. So obviously I didn't need to take any additional steps to "register my shares", but if I want to file seperate claims I now have the forms. So as I said, all my shares become registered when I buy them through my broker.
