Bryan, I see on your user page that, when you joined, you were approved as an Engineering author, which means you can write new articles and make edits (revisions, additions and deletions) in existing articles ... and you are not limited in that role to just Engineering articles. If for example, you wanted to make some changes in a sports article, you can do so.
To become an Editor (like Howard Berkowitz and others), you must make application for that role in some specific field such as Engineering, Physics, History, Economics, etc. If your application is approved and you are granted Editorship, then you can make rulings about the content and/or formatting of articles ...
but only in the field for which you were granted Editorship. Of course, you can still be an author as well., just as you are now.
To make application for an Editorship, send an email to
personnel@citizendium.org and present your qualifcations for being an Editor in the discipline you consider to be your field of expertise ... or you can, I believe, email Larry Sanger directly.
