Trick: Use one Gmail ID as many IDs

Here is a cool trick of Gmail many people might not know about-

Lets say that our gmail ID is  YourGmailID@gmail.com. Now any mail sent to following will go in our inbox. But the trick is that even any mail sent to the following IDs would be recieved by us!


You.r.g.m.ailid@gmail.com (you can use as much DOTS as you wish to and at any location within this id before @ sign)
YourGmailID+321@gmail.com (any number can be used between + and @)

Thus your one  gmail account can act as millions of gmail accounts. 

You can create account with twitter, facebook, myspace or any site using one email. But all email goes to one inbox
