I have been wanting to try DNN for some time now.  And I recently decided to setup a host and start delivering DNN sites to clients.

The way the interface works imo is second to none.  The only other CMS I know of, may be more, that has a similar interface for site management is Concrete5.  But C5 of course is on PHP and from all the ratings I reviewed is far inferior to DNN in many many ways.

That said and with my focus on learning DNN I have started hunting for some books.  The first aspect I want to master is skinning.  I don't want to have to rely on pre-built templates which stifle my creativity.

The books I'm seeing on Amazon are OLD, with a capital OLD.  Lastest skinning book that comes up is "Beginning DotNetNuke"  "Skinning and Design by Andrew Hay and Shaun Walker which was published in 2007.  6yo to me seems like a total waste of money.  I want something that covers the newer version, if not the newest version.

Anyone have any suggestions for good books that are fairly recent which also cover skinning in depth?

Well that stinks.  I'm all for online tuts etc and DNN does seem to have fairly well blanketed resources in that area from what I'm seeing.  I really like to have a complete and thorough manual/resource book however at the very least for reference.  For example with the skinning engine I am only really finding the Skinning 101 4 part series, which is good, but I find it most helpful to see 2-3 different approaches to really grasp a concept especially with how little one can cover in a small tutorial.

What are your best suggestions to get educated on really mastering skinning?
