If you are using one of your Durell diaries for chase-up reminders, then quite possibly you’ll want to issue letters or Emails to the contacts in question to prompt them into action.
If this is the case, then a good idea is to create a diary specifically for chase-ups. See “Diary, Create Extra Diaries” and “Diary, Automated Chase-ups”.
You might then allocate someone in the office the daily task of issuing reminders for all the events still outstanding on that day (or any other date, for that matter). To do this you use the “Diary chase ups” option when starting a new document. See “Diary, Word Processor Links”, and “Mailshot, By Email”.
