QUESTION 1:
Can survey tokens be created to authenticate/identify participants as being members of particular target groups?
That is, is there a way via tokens to also identify each invited participant as being a member of group A, group B, or group C?

QUESTION 2:
Can we determine how long each participant took to complete a survey. Pretty sure the answer is yes, but thought I'd check.

QUESTION 3:
Can tokens be used to direct participants to particular survey sections, entry-points?

QUESTION 4:
Does each survey have its own unique database of invitees? Can these be independently imported/exported?

QUESTION 5:
Can all of LIMESURVEY’s site-specific or server-specific settings be exported and then imported into another LIMESURVEY server to essentially clone the server? In essence, I'd like to be able to set/reset all of LIMESURVEY's non-survey configuration information via some sort of file import, just as I can import a survey via a .lss file.

QUESTION 6:
Are there any direct integrations with analytic packages like R, or is must LIMESURVEY data first be exported then re-imported into the desired analytic package manually.

Hi,
For Q6 => github.com/cloudyr/limer

PS: IMHO it would better to open 1 discussion for each question (or group of questions if same topic)

Q1 => cf. manual User-defined attribute fields

Q3 => As far as I know, NO

Q4 => Yes (1 token table by survey)
Importing/exporting tokens

Hey Ben,
Thanks for your replies to my flurry of questions, and yes, in hindsight I probably should have submitted them individually.
Regarding my first question, if I add a custom field, say GROUP where GROUP can be A, B, C, D, ......., then can I later separate GROUP A survey responses from GROUP B, GROUP C, ..... responses? For BOTH anonymous surveys AND non-anonymous surveys?

If so, this solves my problem in that I can merge the invitees from different group lists into a single list where they're distinguished by the custom field GROUP and essentially survey multiple target audiences at once. Afterwards, I can analyze them collectively or by group by filtering them via the GROUP field. Yes?

You can set a condition (relevance) either at question or group level using custom token attributes (and relevance fields)... but I think it's only for non-anonymous surveys as discussed in this related post

Am really hoping I don't have to tweak every question in my survey just to identify responses as being from a member of a particular group. Assume my token table (the list of invited survey participants) has the three standard fields FNAME, LNAME & EMAIL plus one custom field called GROUP.
Does an anonymous survey omit or strip all FOUR of those fields from the final data set?
Does a non-anonymous survey leave all FOUR of those fields in the final data set?
If each completed survey in a non-anonymous survey's data set includes the GROUP field, then I should be able to analyze just the results where GROUPS = "whatever group code I choose" .....yes?
