Hello!
I attended the open house on Oct 21. AMAAAAZING school.
They let us know that no status updates would be posted until February 15th within the portal where our supplemental application is (since there is no interviews).
They also said if you are weight-listed you will be given a rank at that time. Last year they went through over 300 students total to fill their ~150 spots (including the 25 not at ISU for the first 2 years). I met several students who were weight-listed and were offered in April and in Summer. You have roughly week to reply to these if it is after the April 15, 2018 deadline for original offers. I do know that there were some issues with VMCAS communicating to the portal, so if you send a message on the message board, they are very good at responding! That's exactly what happened to me and they reassured me I had everything.
Side note, I loved this school. I really hope I get in. We talked to students and some of them even turned down their IS acceptances elsewhere in the country. I thought that was amazing along with all of the other cool things I saw; just a side-note for anyone wondering just how awesome this school is
