I am having the exact same NSF Fastlane issue as described in this (closed) post:
(which is addressing this login page: https://www.fastlane.nsf.gov/jsp/homepage/proposals.jsp )
however the "saved a new Login manually" link is broken, and my guess at what it means ("Save new Login") doesn't work for me, and the post is old and closed. When I look at the "web form details" there are a bunch of fields and values that puzzle me, like "ssn" which used to be used by Fastlane but not any more, etc. Has any had success with, or can offer suggestions for, the three fields of NSF Fastlane?
