developer notes

feeder for the moment, in an attempt to avoid including a full account management sub-system here, uses a link to tx for user authentication. To get going on a version for yourself that doesn't require tx, in unit xxmSession.pas change UserID:=0; to UserID:=1; and create a record in table User for yourself.
