I have lots of e-mail accounts I use - @msn.com, @hotmail.co.uk, and @live.co.uk and Windows Live Mail enables me to read them all, however now when I am in e-mail I can access my linked e-mail accounts.  I simply go to https://account.live.com/ and then add accounts to my linked accounts and then I can change accounts by a simple drop down in the windows live mail site (http://mail.live.com).

More information can be found at Link Your Live IDs Together! or at http://www.liveside.net/blogs/main/archive/2007/10/18/update-to-windows-live-account-enables-linked-ids.aspx

Ok, linking is done - but what would you link the IDs for? When you have linked IDs together you will only need to sign in to Windows Live once and can then switch easily between the accounts. If you are on Windows Live Hotmail for example you can check your email on one account and then simply click the dropdown arrow next to your login in the upper right corner and choose one of your linked IDs that are listed their. Without the need to enter a password again you will get to access that accounts emails. Pretty convenient. Unfortunately this only works on the new Wave 2 products, so you are out of luck on WL Favorites, Gallery or the personalized homepage for now - we guess that at least some these properties will be updated to Wave 2 soon though.
