Every time give a new Email Id to Your Friends

Now Friends the very first Trick Of Gmail that I Love the most.
So, it goes like this, say you have a email id yahoo-rock@gmail.com
If Your Friends wants to send you a mail then they will send it at this email address.
Now, Let there be three friends of yours, there may be many, just talk about three at present.
Ram
Tam
Pam
If you want to give your friends a unique email id

For Ram It could be "yahoo-rock+ram@gmail.com"
For Tam It could be "yahoo-rock+tam@gmail.com"
For Pam It could be "yahoo-rock+pam@gmail.com"
So, its simple you could add anything after the initial mail by adding a "+" sign.
As all these Email Addresses yahoo-rock+Ram@gmail.com, yahoo-rock+tam@gmail.com, & yahoo-rock+pam@gmail.com are the same as yahoo-rock@gmail.com

Note: This only works when you are sending mails, Not for logging into your account.
Enjoy.....
