Go to http://op.pokemon-tcg.com for information about sactioning events and player ids. There is a program for the PC to run events but it isn't quite workable yet in comparison to the DCI reporter which can be used just as good.
I just wish there was a OS X version Tournament Manager... or, if at least my Palm version of Tourny had reporting capabilties. Once again, Mac and Palm users are neglected (Thought I'd changing it up a bit from the usual complaining ).
