Then you're in the same boat I'm in! You can send in your committee letter later, long after you've submitted your aadsas application. For example, I submitted my AADSAS in mid-late June and got my number already. The application got forwarded to schools last week. However, my committee later won't be ready until mid-August! So, when AADSAS finally gets hold of my letter it'll send it out as a separate mailing to all the schools again. Hope this helps.
