Forget doing escrow here as frankly speaking, no one will use your escrow service here because of an obvious reason. And reputation isn't build but earned. An intentional way to build reputation is not a wise thing to do. Let the community trust you based on your works and contribution.
very well said. he cannot do some escrow because he is only a newbie but i think he can still do to offer other service just like what he said that he is willing to help for online problems. but escrow? i dont think there will be someone who will avail that from him.
