How to use your email for Windows Live services
Every now and then my friends keep asking me that how do I use my Gmail address on MSN Messenger. All I have to say is that it’s not a big thing! All you have to do is create credentials for your email address (not only for Gmail, any email provider). This way you can access almost all the Windows Live services.
To create credentials, fill this sign up form and get your email activated. Finish! Were you expecting more? :P If you are a Gmail user, like me, then you are lucky to have one email address that can be used on Google Talk, Yahoo Messenger and Windows Live/MSN Messenger :D . Wherever you are required to use a Windows Live ID, you can use this email (you just registered it). It gets quite easy to manage things with one email.
