thanks, Thats one of our option as we also might consider, the question is what will be more efficient either to fork the poll plugin or checkbox plugin.
when using polls the amount of voters are seen as well as the result (which makes it no usable for exams, we are aware of partial solition:
this is not suitable as is), also there is no chance to make revision comparision to right answer as with checkboxes
Very much appreciate additional feedback on that also from @cpradio and @downey THANKS
