In order to update the discpline system (May 31/2023):
a) Add the disc_comment with:  mysql -psezme YOURDB < disccomment.sql

b) Copy the comment field from existing disc_ident table to the new table using: copyComment.pl script.
Normally runs in cgi/discpline.

c) You can remove the disc_ident comment field if you wish. Scripts won't use this field any more (Theorretically speaking!)
