I was pleasantly surprised to see that DNN 5.0 was released. I have already downloaded it and have taken it for a spin.  My first impressions are that it is good.  I have run into a couple issues though.

1. I tried to include a bunch of modules while I was running through the install wizard.  That caused the installation to error out.  I even tried to just install 4 modules and got the same result.  It looks like the best thing is to just pick a couple.
2. I noticed that once DNN is installed you don't have the ability to add the common DNN modules like I did with the older versions of DNN.  Now don't get me wrong, I can still download them from DotNetNuke's site and install them, but it used to be easier.
3. The Extropy skin's are pretty bad.  They break and look bad in IE7 and are unpredictable at best when you add new content to the pages.

Okay that is all for now.  I am going to continue to dive into DNN 5.0.  I know some of the above comments are negative, but I am still excited about the product.
