Recommendations - MIT

Two questions regarding MIT recommendations:

  1. Does my student send the recommenders the link to the sign-in page for the recommendations? Then they have to register on the system?

  2. Anyone know when they are due from teachers for EA? Do they have longer than the 11/1 EA date?

Upon further research, it looks like they can be submitted via Naviance. I assume that means submitting just like other schools (like those on Common App) and not via MyMIT.
