I am brand new and have this exact same question. If I cannot reuse the resources for other courses, it will make using Moodle very difficult for me. I hope we get some responses to this question.
You can copy content between courses using backup/restore.
In moodle 1.5, there is also the ability to 'import course content'.

how about sharing content?
Not at the moment as far as I know, at least I don't think there is an official patch for it. I have a feeling that someone made a block maybe that shared resources? But I may have dreamed it

Audun's block works very nicely for moving content around and between courses. IIRC Martin mentioned something about putting it in 1.5?
