Logging in to multipile Gmail ID's on the same browser

Dont we all have more than 1 Gmail Id ? I am sure most of us do. We are all comfortable with GMail and we are also comfortable with the fact that we can have an alternate Gmail id. So one would be an ID with our name in it and and other could be something which would interest the female you met on chat or mislead the cyber stalker on the prowl (you could add more reasons in the comment box below).  . For e.g an ID like MachoMan@gmail.com for males and sweetangel@gmail.com for females and also for 'not so macho' males. Now the tricky part is to maintain 2 ID's. If have to check mails from different gmail ids you have to individually login and logout of each ID.There is an easy way to do this.
Login to www.google.com/accounts

and click the edit the Multipile sign-in option which i have highlighted in the image above which will take you to a page like this.

Select the 'ON' check box and select all the options given below it and then click save. Go back to your gmail

Click the drop down arrow right next to your gmail address on the top of the page. You will get a clickable option of 'Sign into another account'. Which will take you to the normal Gmail login page. Enter in the Username and the Password of your other Gmail account. Click the drop down box again and you will notice that your default ID is also featured there. Click on the email ID's to switch between 2 email ID's.
You can add as many Gmail ID's you want.
