I have to admire the amount of work you’ve put into this. In that regard, it reminds me of a counter-culture publication from the 60s. Was it “Whole Earth Catalog?”
Seems like you ought to be able to make some money from this, if you wanted, and I don’t think there would be anything wrong with that.
I bet more people would buy it than would print it out.
BTW, you allow downloads, so why the security?
To control the access to FReepers and people they recommend. We have to pay for bandwidth and storage. If it was a public site it would quickly be overwhelmed and nobody would be able to get anything.
