Site Licensing

Most of the Ellipsix website is made available under one of two Creative Commons licenses, as described below. The motivation behind this licensing scheme is that most of the website content is intended as reference material, and the normal copyright law would put rather silly restrictions on people's ability to use and share that content; at the same time, it's only fair to give credit where credit is due, which also means that the Ellipsix site gets a bit of free publicity in return for each use of its material. However, the same web pages that present this reference content also include some elements that are integral to the online image of Ellipsix Informatics, which need to be more tightly controlled so that they don't present an inaccurate impression of the site.
