In the heading of a course, you mean, so that it displays above everything else? Or just in the center, above the sections?
Whatever the answer is, I believe that noone has tried that before in Moodle 1.4. I can tell you that the latest 1.5 development version does include facilities that would make it relatively easy to do what you describe. I may even be doing something like that (or possibly add blocks to an activity) as proof of concept. But what exactly do you want to do?
I suggest finding some other way to make things work, because moving the whole block up there is going to be more pain than it's worth.
Before I call print course block, I am calling block_load_class('news_items'); and this is working (or it doenst cause anything to crash)
Thanks for the help.
