I would like to invite participants at random intervals over time.

Here's an example:

If I have 1000 employees, I would like to survey each employee once per year, but at random times. (e.g. 20 random employees receive a survey invite each week for 50 weeks).

Could this be coded in a plugin, or another way?

Thank you, in advance!

Well, as everyone is supposed to participate once and only once, I would take a list of employees, give each of them a random number of 1-1000 and then each week send 20 invitations, starting from 1 and ending with 1000.

I don't think this is something a plugin could do.

Thank you for the suggestion. I appreciate it.

Since you probably don't want to send invitations manually each week you can try to adjust these cron jobs for automating the process of sending Limesurvey email invitations:

How about adjusting holch's solution to only generate 50 numbers and assign them to 20 employees each? You can then run the cronjob weekly and use a date function to check if the current week == a random number [1,50]. That random number can e.g. be stored as additional token attribute.

Thank you. I like this approach. I could setup the survey and run it over the course of a year. At the end of the year I'd update the employee list and re-launch.

Much obliged!
