Persist custom registration information with Profile API
<p>I've seen examples of producing a custom registration control which persists its information with some extra fields (or a table depending on the problem) in the corresponding Sql Server.</p>

<p>It's also said that there is a way to do the same thing with the Profile API (persist custom info in a registration control). Is there a walkthrough for this?</p>

<p>Thanks</p>
