Poll option with 0 (zero) doesn't appear in poll list
I need a small help on Discussion Polls addon. If my poll option is empty, it doesn't shows as question and that's right but if I put 0 (zero) then also it doesn't shows on preview. That means it acts as empty field. Is there any way to solve this problem.
I also need 0 option in examples like this:
How much beer you drink per week (all in liters):
options: 0, 1-2, 2-4 etc (and 0 doesn't appear in the list)
I appreciate your HELP.
