What was e-mail notification 1 supposed to have been?

<p>I applied last night (Finally...quite later than I had initially expected...is it still considered a relatively safe time to apply to avoid the rush of competition?), and I've received, oddly enough, e-mail notifications 2 and 3, but not 1. Is this a problem?</p>

<p>I think e-mail #1 could have been signing up for the online app account</p>
