<p>Harvard, MIT and UC Berkeley, as the first universities whose courses are delivered on the edX website, are "X Universities." The three institutions will work collaboratively to establish the "X University" Consortium, whose membership will expand to include additional "X Universities" as soon as possible. Each member of the consortium will offer courses on the edX platform as an "X University." The gathering of many universities’ educational content together on one site will enable learners worldwide to access the course content of any participating university from a single website, and to use a set of online educational tools shared by all participating universities. </p>
<p>If you have previously signed up for an MITx account, you already have an edX account and can log in with your existing username and password. If you don’t have an MITx account and received this error, it's possible that someone else has already signed up with that username. Please try a different, more unique username – for example, try adding a random number to the end.</p>
