TFS express access for remote users
<p>I have a <code>TFS</code> express configured on my windows server. Is it possible to invite a remote user on his email address, so that he can connect to the server and access project collections? I had been through few similar SO posts, and tried to explore almost all parts of the admin panel, but could't found such feature. </p>

<p><em>(I know this is available in case of visualstudio.com, but I need to invite a remote user to my locally hosted TFS)</em>.</p>

<p><strong>Question:</strong> 
 - Is it even possible to allow remote user to access my TFS?
 - If so, how to authenticate him? </p>

<p><em>Other Info:</em> TFS is perfectly configured, and is accessible remotely as <a href="http://xyz:8080/tfs" rel="nofollow">http://xyz:8080/tfs</a> </p>
