Help! Registered the Same Username Twice?

Applying to College Common and Coalition Application
1

<p>While registering my name under the Common Application, I accidentally pressed the back button, and submitted my registration form twice. </p>

<p>I only got one email from the Common Application website, stating that I had successfully registered, but is there the possibility that there are now two accounts separate under the same username? If so, how can I contact the CommonApp about this?</p>

<p>Am I just being paranoid? Thanks!</p>

<p>It will only let you register a username once, so the second submit must have not gone through.</p>
