I'm starting a group blog with people who don't really know what they're doing in wordpress and would like to be able to write in some basic instructions throughout the post.php page to guide them through the posting process.
Specifically I want to be able to explain to them how to create new catagories in the sidebar when posting something. What php file do I need to edit to add some text to that part of the post.php sidebar? I can't seem to find the right spot that controls the formatting for that sidebar. Which file in wp-admin does it?
