If you're like me you have multiple Gmail accounts, and not being able to access them all at the same time sucks ass! Google released a multi-account feature last year that I'm just finding out about so I thought it would be cool to share... enjoy!
Now, you can visit google.com/accounts and click the link next to "Multiple sign-in." After you sign into your first account, you can sign in with up to two additional accounts from the new accounts menu in the upper right hand corner of Gmail, then easily toggle back and forth between them. You can even open multiple Gmail tabs — one for each of your accounts.
