I think polls are sorted automatically - alphabetically by headline. In some cases - like here (
http://elementscommunity.org/forum/index.php/topic,33777.0.html) -this can be bad, because not the number of options should determine order, but the first letter of the question.
I created 3 polls to show that sorting mechanism. When I change text, I can change order. I created AAA first, then ZZZ, then MMM. You see they are sorted. Number of options plays no role.
Problem may be solved by adding "poll 1", "poll 2" to question texts - but which user knows this trick ? It´s not intuitive.
I hope, we´ll find a solution to this problem, maybe it´s a simple admin option, or a tool, which allows sorting.
