[[tron]] suggests that non-developers should be able to post content to a staging area, to be approved (possibly after editing) by developers. I like this idea a lot.
For non-developers using [[anonymous CVS|wiki/todo/push_wikisrc_to_anoncvs]]: submit a diff to `netbsd-docs@`.
For non-developers using a web browser: the ikiwiki discussion subpage and/or [[!iki plugins/comments desc="comments plugin"]] may point toward the solution.
