I see many campaigns that allow AltcoinsTalks members to participate in their signature campaigns as HOMT, TOZEX, SwapZilla, EMIREX ...
Or do you mean that projects will directly ask the highest ranked members to use their signatures and then pay in ETH/BTC? I don't think this is the time to deploy that, nor will it promote the development of the forum further. It only makes the members lose their sanity and find ways to raise the rank instead of contributing to the community.
