Apologies if this has been answered elsewhere, I couldn't find it if it has!
I have a user population of around 10k and I want to be able to filter them, say by location and business unit, and then select a number of users at random from the filtered list.
For example, I may have 800 users in 'technology', in the UK, and want to survey 300 of them at random. Can LimeSurvey handle this type of selection?
Further to that, I want to restrict the number of surveys sent to max 3 per year - can I keep track of the number of surveys the users have been selected for and use that to exclude them from future surveys? I realise this might mean that I can only select 200 of my users because the others have already been asked 3 surveys.
