Since only one day is gone and all 15 copies are gone are also, I'll extend this free offer through Monday. I will probably be using a new file sharing service, though,and I may have to send the links through email. If you missed out on the first fifteen, just contact me by private message, or you can email me at firstname.lastname@example.org and send me your email address. Either Tuesday or Wednesday I will upload it and email you with the link.
I am editing this to reiterate that, should you decide to email me for a free demo copy, please ONLY use the email linked above. I just tested it and it worked for me. Someone said they emailed me, and I did not receive it. I don't know what email account they used or where they found it.
Thanks everyone. I tried to make this post as short as possible to limit the number of typos and grammatical mistakes I invariably make as a non-blogger.
