I think you would be able to make a valid contribution, exactly because you\'re just starting out, so you should be able to note down what got you stuck as it happens (I\'m starting to forget how difficult things were when I started out, even though it wasn\'t actually that long ago).
I presume that you\'ll not be jumping straight in at the deep end and trying to get OE up and running (though by all means do so, it\'s not that difficult), but certainly documenting/making comment on everyday use of OZ would be good.
The main trouble you might have is that OZ on the 5600 is unstable, though I don\'t think it\'s as unstable as some people make it out to be. So you may be straight in there having to report (and fix?) bugs.
