We needed to add two new fields (or new columns): phone numbers, and student numbers (or student id's).

1) Add columns to tables mrbs_repeat and mrbs_entry (or mrbscustomsized_entry etc):
alter table mrbs_repeat add column student_id int;
alter table mrbs_entry add column student_id int;

2) Edit edit_users.php, mrbs_sql.inc, edit_entry_handler.php (we also edited search.php and report.php.  I suggest you search for repeat_id  (or private if you are using the latest version with it such as the SVN) and use those entries as a guide for creating new entries.
