How to submit a new port ?

hi, I'm not sure this is the right mailing list (from the archive it seems so), I have made a new portfile for an open-source project called playerstage (see playerstage.sourceforge.net) but I don't how to submit this port to the main tree (macport !) ? I even offer to maintain this port for a while but there is no documentation on how to submit a new port. The two portfiles are here: http://www.ai.sri.com/~vincent/Port/science/player/Portfile for player http://www.ai.sri.com/~vincent/Port/science/stage/Portfile for stage R.
