I think, as already mentioned by other members previosly, we should have a special treat from GG when is our birthdays!! It would increase the sense of community and connection between people within the network.
It could be a little payback award, maybe according how participant the user has been within the community?
It could be a raffle draw, with different prices and everyone wins something... From a first prize iPhone to 50 points payback?
It could be that who is interested in this idea, would pay towards it a little contribution such as £1/month?
I think we can do so much considering the power of the community, it's all about good ideas!
