I offered the money into the pot because it was a community run competition.
I am not against Nokia offering other prizes but this should not effect the pot as collected by community.
If I had been entering the competition as announced finding out that a cash prize was not on offer would be rather frustrating.
I think the non-monetary prizes should be an added incentive and do not mind the money and trip/N900 going to the overall winner of each on top of a some prize money.

I would have chosen Option 1 had I seen the poll.
