.NET Nuke

A friend of mine who is big into the whole .NET thing pointed me to a product called DotNetNuke. I'm told there are other variations of this type of product in different languages (PHP and ColdFusion). The whole *Nuke product is a open-source, skinable, content management system that is completely generated by a back-end database. This is a perfect product for one of my clients that needs to have the ability to add/remove pages without needing to know HTML. They use Contribute now, which is OK, but they could something more powerful and easier to use. This product might do it. I'm in the process of moving their web site over to DotNetNuke to see if it will work for them. I'm guessing they'll need to have a CSS skin designed for him as they often have people with accessibility issues visit their site.
