Grants.gov Error Messages and Attachment Names

Well I learned something new about the Grants.gov system today. The meat of any grant applications is a series of .pdf attachments to the application. Attachments containing special characters (example: &,–,*,%,/,#’, - ) or with a file name of longer than "approximately" 50 characters may cause the application to be rejected by the system. Read more about it here: Filename Attachments - Adobe & System-to-System (S2S).
