Microsoft plans to discontinue its own technical support forums on CompuServe in favour of Usenet newsgroups. The groups, which will be activated today, will be free, the company says. April 20 is the last day for Microsoft-sponsored CompuServe forums. CompuServe plans to offer some Microsoft forums, but after April 20, Microsoft won't run them. Users can access the new newsgroups at http://www.microsoft.com/support/.
