I reserve no copyright or patent rights to any of my creative work. As far as copyright and patent law are concerned, I grant you permission to do anything with it that you wish. See

This is a perfectly free, noncopyleft licence. Because it is all-permissive, it is automatically compatible with any other licence. If you're keeping track of Wikipedians whose works are compatible with other licences, then feel free to add templates and category headings to this effect below.
It is not possible for me to place in the public domain anything that I do not have complete rights to. For the most part, therefore, my work on Wikipedia cannot be in the public domain. Given the permission above, you shouldn't need anything to be in the public domain anyway. However, if you want me to place something explicitly in the public domain, then ask me, and I will do so if it is possible.
