Well, I have finally figured this one out!
I have researched how to remove the time, date, and author from posts for months. There are plugins and coding to do this, but up until now, none have worked for me. Even the discussion on the WordPress.org forum have not helped, until I found this one today (August 9, 2011).
Just follow the instructions, and it should work for you too.
By the way, it may not make sense for you to remove the date, time, and author from posts. If the chronology or the date of your posts are important to the content of your writing, it is probably a good idea to leave them in. I wanted to remove them from this site, because the posts are more like entries in a library of Resources.
