Is it possible to send a test person a second follow-up exactly 4 weeks after completing the first questionnaire?
Limesurvey is still relatively new to me, so any help would be appreciated!
This is not built-in.
You may do it by yourself.
Create a small script (php, or other) to query the LimeSurvey database (via API or directly) to get the "four-weeks-participants".
With something like "phpmailer" send the emails.
This script you call by a cron job each night..
There are a lot of providers of free cron jobs.
