As a community we all contribute and build up a pool of knowledge, support options etc. This I call our community asset.
Unlike a commercial company tikiwiki.org does not directly benefit from its assets.
As seen on Wikipedia Book it is possible to merchandise the content generated by the community. All parties will benefit from such a solution. 10% of the printing revenue goes in this example to Wikipedia Foundation, the rest is for handling and printing. As a user I know there would be a need for printed docs.
