Birthday threads are created automatically everyday at around 00:04
They are only created for members who:
- have visited the site within 21 days before their birthday.
- have at least a day and month set in their birthday settings.
- have their birthday settings set to either 'Display Only Day and Month of Birth' or 'Display Age and Full Date of Birth'.
Note that 'Happy Birthday' emails are automatically sent out to anyone who has their day and month set, (and
allow admin emails), regardless of time last visited and display settings.
Why do only some members get birthday threads?
