Wiki Articles are standalone works written by one or several authors. These may be technical papers, journal articles, or other pieces. As an article they are designed to stand as a permanent work of the author(s) and so are locked and not editable by teh community. These are kept in the Articles Wiki Section in various Chapters. If you have material that should not be editable by others, then it's best to submit that as a Wiki Article or Upload the file in various formats to the Outdoor Ed Library.
