Finding a solution to puzzle 1 would be great, but the solution would not be perfect as I cannot alter the subject line of the ODUE notice. My ideal solution would be not to send the ODUE notice to leavers at all, and instead send a separate notice to them using the patron emailer. So I need TT code / a rule to prevent a notice that *should* go out from being sent. [% IF (borrower.dateexpiry !== CURDATE() %] <standard ODUE notice is sent using a subject line appropriate for current students> [% ELSE %] <no email is sent, to the leaver, and my LEAVERS_FIRST notice is sent via the crontab using the patron emailer> [% END %] I am working to significantly improve messages to students and being able to use TT code / rules to **prevent** a standard Koha notice going out would be great, but I have no idea how I can do this. I'd appreciate any suggestions... indeed, is this possible? This email and any attachments are intended solely for the addressee and may contain confidential information.
