The creator of the survey is provided with an option of obtaining statistics of his survey. The statistics consists of number of responses,incomplete responses and so on! But the creator of the survey has no idea what is the user's opinion on his survey!

I am pretty sure that in 1.90 I had negative intergers for some of my answer codes. But in 1.91 this is not allowed - and the documentation is very clear on this: http://docs.limesurvey.org/Adding+answers+or+subquestions&structure=English+Ins tructions+for+LimeSurvey

This is not a huge problem, as I can always recode the answer options, when I export the results to excel or R or SPSS or what not. But it is a minor inconvenience that I am curious about; is it necessary?

Sometimes it makes sense to code with negative numbers. E.g.
Like a lot (+2)
Like a litle (+1)
Neutral (0)
Dislike a litle (-1)
Dislike a lot (-2)

I created a new survey with an end url.
Afterwards I clicked in the overview on the end url link.
The end url link opened in the same browser tab.
On the landing page I clicked the browser back button to go back to the LimeSurvey administration site. By this action the data was sent again and the survey was created again.

Lime Survey needs a better statistics model. Many people would pay if one of these was added. I need it to work on my job.

It looks like quite a bit of information is duplicated in many questions, which makes the report bigger and harder to digest.

First of all I would like to point out that my English is not as good as my German grammar and may contain errors. (I give my best)

In my opinion, are qualified and professional statistics, some advanced views in the statistical analysis required (on request, alternatively).

In non-graphical representation:
For example, it may be important if you specify 2 or more results can be side by side.
For example: If the question is, which politician do you choose, it is important to know, how many people who answer to this question, come from which country or which nationality they have. (as a question and / or IP) answered the questionnaire).
and so on.........
