In preparation for the upcoming PASS application cycle, I have been contacting my evaluators for LORs with general guidelines.  When they submit to PASS, can they upload a PDF version of LOR?  Or do they have to copy and paste what they have written to a window in PASS?  The reason I am asking this is because I don't know if I should ask them to sign by hand at the end and scan.  Please let me know if anyone knows.
