I can login just fine. Have you been able to log on before? I don't think that the committee necessarily meets on the 15th of the month, just that decisions usually go out on the 15th (please correct me if I'm wrong). In the past people have gotten acceptance a day or two after the 15th and their letters were mailed on the 15th, I don't think the committee would meet on the 15h and mail out letters the same day. Also, I don't believe that once you're accepted you will be able to see online, I think you have to wait for the letter. All you will see is "Under Consideration."
Yes I've logged in before...not sure what is going on. Yes, I believe applications are sent out to committee members on the 15th, they make their decisions, and then letters are mailed on the 15th. & yes you're probably right about online status
