For those that don't know, the Microsoft Partner Program has a program for ISVs (Independent Software Vendors). ISV is just a fancy acronym for a company that produces packaged software to sell.
It looks as if they have launched a new website called Virtual Towers. The main page is a flash (when are they going to start using silverlight?) interface giving you access to all sorts of free training. In particular, you can get Webcasts on SQL Server 2005, Sharepoint Services, Visual Studio 2008, ASP 2.0, etc.
In addition, there is information on other promotions, such as their Business Intelligence seminar, where the first 50 who finish can get a Microsoft LifeCam NX-6000.
