I have my survey (a multi-wave study - baseline, two weeks, 6 months) set up so that the mail schedule (PHP embedded at baseline) sends out mail 6 months after calling up baseline.
However, I know that the admin period can only be set to a max of like 90 days. Can I still have mail set up to go out 6 months after baseline with this?
My solution was to manually extend the admin period once 89 days had passed. Will that retain all info/collected data/mail schedules?
