Krozruch has not yet, and may not in futute write posts using the CC0 license and so this is a test post to check the license template page. CC0 is a highly-philanthropic license for content which may be used anywhere in any way with no limitations. It is not necessary to credit the creator. This means that, for example, photographs may be used in posters and promotional materials where visible attribution may be problematic.
