Hi

I am trying to figure out if/how I could do the following with Limesurvey:
- I have a pre-defined list of a few hundred survey participants
- every working day I need to select a random sample of X participants (randomization can be done beforehand via Excel if there is no other way) and automatically send survey invitation to these X participants; the next day the same with another sample

I found www.limesurvey-templates.com/automatical...nvitations-p-49.html but this does not seem to do the job (sending invitation only to a subgroup each day).

Any help would be very appreciated

This is rather simple using remote control (rpc2). Just make the selection in php/python/R or whatever language, and add the selection using remotecontrol. Then invite the participants, again using remotecontrol.
