Me again! Been a while.
Same situation here. The “before confirming your enrollment” is suspicious, and worse: if you click the link to register, the description on that page says things like "meet OTHER admitted students" and "adjust your class schedule". I sincerely think this is a mistake on the auto email list, as I have not been interviewed or heard a decision on my program, and I am assuming rejection. That being said, they're really getting my hopes up, so, if it's just another generic one, ouch.
Let me know if you email asking about this one or get any other news!
