as many of you know, ROCK is a fitness EXPERT. a few years ago, i bought a .com name with the intention of someday starting a site with exercise/diet info. i want to sell the info for like $50 or something. for the $50, they'll get a excel file and a .pdf file with all the info. or maybe i could password protect an area on the site where they can get the info. how about password protecting a .pdf file!? i know i could print and mail it, but i don't want to get involved with mailing stuff all the time. this is the electronic age, anyway.... what's the best way to sell info like this? if i just email a person a .pdf file after they pay, they could just forward it to all their friends. what's the best way to do this? p.s. special deal for ET members once the site is up and running!
