Sample suggestions notices should be part of installer/data/mysql/en/mandatory/sample_notices.sql. I'm assuming a separate notice would be required to duplicate the functionality of the now-obsolete mail_suggestion_ACCEPTED.tmpl, mail_suggestion_AVAILABLE.tmpl, mail_suggestion_ORDERED.tmpl, and mail_suggestion_REJECTED.tmpl?
Patches pushed, please test
I have these notices on my updated system - so I'm closing. If someone with a new install doesn't have them they can reopen.
