How can members add comments to polls?

Is there a way for members to add polls for other members to not only vote but to comment too?

Hello, members can already comment on Polls .... just click the poll title and it will take the user to that actual poll page where members can rate and comment the poll etc.

Is there a way for members to select multiple answers?  That is what I am really looking for.  

Anyone know if this is possible?  Multiple answer selections?

Same question : how can members select multiple answers ?

Something strange happening with the poll I created : I can choose any answer, but only the first one is taken into account. I tried to select another answer (with a different profile), but only the first answer is counting.
