I know that is a recursive topic, but I think that if we could have a NING poll system it would be a great stuff.
Contest and polls are awesome instruments to create participation in our site.
We have used, till now, several hosting service (now wofoo) but there are some problems: voting system are linked to IP addressees, but it's enough to restart routers to vote an another time and using mobiles it's very easy to vote several times.
More, we have an open site to visitors and we have to hide contest page to avoid that external people can vote.
I'd like to have a voting system linked to ning access and hidden results.
I hope that Ning consider this, thanks in advance
