I dont think it is necessary to join Merawindows for becoming MVP. Merawindows is a forum supported by Microsoft india and according to Microsoft MVP award is
Microsoft Most Valuable Professionals (MVPs) are exceptional technical community leaders from around the world who are awarded for voluntarily sharing their high quality, real world expertise in offline and online technical communities. Microsoft MVPs are a highly select group of experts that represents the technical community's best and brightest, and they share a deep commitment to community and a willingness to help others.
merawindows forum can help you in getting MVP award
but there is more than getting award there on forum
its all about sharing your knowledge and helping others
