Sumit, welcome to the Success Community! I'm following up on your request to join the Premier Central group. This group is reserved for Premier Success customers, but there are a number of others here on the success community we'd love you to join, including bit.ly/SalesforceGettingStarted, bit.ly/SFDCReleaseReadiness and bit.ly/SalesforceSalesCommunity. If you actually have a login to a Premier account, please let me know and I'd be happy to add you. In the meantime, here's a video that will give you a great overview of the community as a whole: http://www.youtube.com/watch?v=bDga1EE6IGI. It'll also show you how to update your profile with your picture and/or company name - this helps other community members find and collaborate with you.
