Started playing with DotNetNuke last week. It’s an open source portal system, similiar to phpnuke.
I must admit I find DNN very interesting. It even allows very deep localization which is very useful for polish customers. Hopefully I’ll be able to present a production grade website built upon this framework for our company.
The only glitch I encountered is using serching, every time I get an “object reference not found” exception. I even tried adding a custom page with search results module embedded but it didn’t help. I guess it will take me some time.
