How would you like to get your hands on a robust and easy-to-use ASP.NET based development infrastructure with built-in personalization, role-based security, advanced management tools, rich native .NET API, WS support, tons of sample code and documentation, which is supported by a *major* vendor, is FREE, has great performance and scalability?
Well, take a look at Windows SharePoint Services (WSS). It has been officially released and is available for download from the Microsoft site. WSS replaces the somewhat shaky "Sharepoint Team Services" with a totally rewritten, ASP.NET based solution which kicks ass! And best of all - WSS is included in the Win2003 license, so you get it at no extra cost.
Definitely worth a look!
