Tadge has been up to some serious good with his wiki project.  You should give it a look the next time you’re planning a training.  For example, this Bloglines tutorial is solid, and there’s plenty more where that came from.  Of course — it is a wiki — which means if you see something that needs fixin’, go ahead and fix it already.  (I’m sure they won’t mind.)
    Check out the wiki — and give thanks to folks like Tadge and his team.
