1. Download the software and/or books in which you're
interested. These downloads are free and
you're under no obligation
what-so-ever
to purchase anything. The programs are fully functional as is. There
are no ads, subscriptions or other devices hooked into the
software.Yes, you read that right. For a long time these products were
offered in
the
commercial world at the "going rates" which typically varied between
$50 and $300 per title. Not anymore. You can read
about the decision to make all of these titles freeware in the FAQ. The very small amount of
money made on the sale of print textbooks goes to offset the costs of
maintaining this website.
2. If and when you've decided that this neat stuff
is truly useful, you might consider a modest donation
to further development and support of free and open resources. Totally
on the honor system. Let your
conscience be your guide.
