Not really,you will have to advertise to let them know you are looking for people to work on one
But yeah,minimum number of coders you will want to have is 2,1 will not be able to spot any mistakes in the code,and hopefully the other should be able to spot it....
I mean,look at NS,they got 2 great coders on....and of course here we have harSens and PcJoe ,and now look how good the code is
Too bad we really can't tweak the netcode much....
