Reading through the post_class() text, it appears you can use an array to put text in there, so like this:
post_class('foo bar');
That would be correct, and I have tested it out, and it works fine.
How do I get the post's author's name in there though? I've tried using the_author_login() but it doesn't work. $post->post_author gives the ID, not the name. Can anyone help?
Thanks,
Richard
