Since red and Yellow server are dying out more and more and almost every new player joins blue server i think it would be a great step to get rid of the yellow server and transfer peoples characters & pokes to red so the community will get divided on 2 servers kinda equally which would help bringing new players in fairly equally; right now every new player will most likely join the most populated server; a bigger amount of people online will improve trading and pvp which are the main reason why most of us play pokemon as an mmo :)
