to share files on the mac you check a box in the sharing panel of system preferences. click that. you're pretty much done. okay, so i want to share the files on my pc. i found a similar check box on the pc. i checked it. no joy. so i asked john. he didn't answer. he just came over to my house, took over my desk, and started doing stuff. for like two hours. when he was done i could read the pc files from my mac. yay! i have no idea what he did. but it involved a fair bit of grumping. i suspect it would have been cursing if the boys hadn't been home. pc's suck. and apparently it's my fault. well excuse the shit out of me for expecting these things to work out of the box.
