why can't I join the Wolman 2010/2011 group on Facebook?

<p>it says that the group is open to all members of the Johns Hopkins network.</p>

<p>i put, in my education and work info, that i am part of Johns Hopkins University 2014, but still i cant join the group.</p>

<p>what is going on?</p>

<p>You have to add the actual network using your @jhu.edu email addy.</p>
