Thing is, I believe that even the smallest charge could prohibit some users from obtaining the sets, from fear of paying online.
There are some users that wanted me to send them discs, but had absolutely no idea about how to pay (I was like them too, until I was "forced" to learn in order to get in my hands a copy of "Deleted magic".
So I really think the "pay it foreward" system could work in a community such as ours, where our goal is a common one: To spread the OOT around.
Good work ADigitalMan, I hope I will be able to get a copy of your set in my hands soon.
