Dear Dr. Joo - Here are the letters.&nbsp; Unfortunately there was one that I could not actually edit much because it was not clear to me what the purpose of it, or who the intended recipient or the author were, or whose project was being referenced.&nbsp;&nbsp; I'll be glad to work further on it if you can submit again with clarifications.&nbsp;&nbsp; Thanks again for the privilege of working with you.&nbsp; RebeccaTDE
