Is it possible to have have one login link to many other sites?
<p>So a client has asked me if I could build an interface where they would have their account and from there be able to link and see all there other accounts on other sites, like sportsbook.com, etc...</p>

<p>I would create this in php and got somewhat of an idea.  If you know a great way that I could go off this please let me know!</p>
