Now that we have set that aside I would like to answer this question:
Can I make it more obvious that I am the author?
(1) The first method is to choose a theme that has an "authors" page template.
(2) The second method is to create a Category for each author's name and have the author's assign their categories correctly to each post they make.
(3) The third is for each Author to simply type a byline into each post. Example: The Wonderful Post I've Ever Read by John Doe
And IMHO as these options do exist insisting that staff edit each and every theme is not likely to happen.
