I just spent the last week learning Mambo. It is very powerful - but very confusing to the new user. I had almost given up several times because of the Admin interface that doesn't make a lot of sence. But once you get past it's quirks - it is really great.
As a result I wrote this little tutorial for new users while I was still in the pain of learning and posted it in the Mambo support forum. It seems to be very popular.
Thanks for the tutorial, Marc. I've been looking for a good CMS recently, but decided against Mambo for now due to the learning curve and sloppy admin interface. Hopefully your tutorial will change my mind .
