eems strange to me that no one who uses Lime Survey has responses coming in from IE.
I can only speak for me, and in my market, incidence for IE was 0,85% in April according to Statcounter. So for me it is not worth testing the questionnaire on IE anymore. I will accept to exclude 0,85% of potential respondents for the advantage of not having the additional work.
In other markets and for special target groups IE might be still relevant though.
Seems like in the US the incidence is almost 5% still (who the hell is this, even for the whole of Africa it is below 2%). So in the US I would consider IE still relevant and would probably test the questionnaires on IE.
Now in Germany, where the Limesurvey GmbH is located IE is still at 4,85%, so I guess they have to test on IE there as well.
Quite interesting to see the local differences:
