Dot Net Nuke..
About an year ago I worked on a clients DNN site and never liked it.

I hosted my site on Yapill.com and am going to experiment with its features.
The installation was not too bad on GoDaddy.
Create a folder in the root. Set it as application directory (Virtual Directory).
Update the Web.Config with the appropriate connection string. (Host Name = Server Name ! bummer )
Go to your_domain.com/Created_folder/install/install.aspx.
If you configured everything correctly, the installation will be done in under 5 minutes.
