You understand, the moment I start earning dinero I would expect to hear from the lawyers of the Tolkien estate. As someone mentioned here recently, the Brits vigorously defend their copyrights, and the Tolkien folks especially.

Don’t earn dinero! Just form your own nonprofit. The SBII fund to support unpublished writers. SBII = Support Bob Ireland Initiative
Have all who download your writings feel free to support your nonprofit with any donation they choose. Of course you must compensate the administrator of the SBII.
