My intention in creating HammondWiki is to create a repository of freely shared and freely sharable information.
I wish that I didn't have to deal with copyrights, but suspect that I should.
As of now, the material on HammondWiki is released under the OpenContentLicense (OPL). (Thanks to CliffordAdams for suggesting the OPL.) The material is copyright by myself and the original authors of the material.
I am open to alternative suggestions, and would certainly like to see comments from someone more experienced than I.
MeatballWiki has also had some discussions you might find interesting. See 
MeatBall:MeatballWikiCopyright for lots of discussion (but no final answers).
The final policy was inspired by yours, actually. -- SunirShah
