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 bestfriends@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
Manoj
Vinod

Ganesh
 
If you want to give your friends a unique email id
For Manoj It could be bestfriends+Manoj@gmail.com
For Vinod It could be bestfriends+Vinod@gmail.com
For Ganesh It could be bestfriends+Ganesh@gmail.com

So, its simple you could add anything after the initial mail by adding a "+" sign.
As all these Email Addresses bestfriends+Manoj@gmail.com,bestfriends+Vinod@gmail.com and bestfriends+Ganesh@gmail.com are the same as bestfriends@gmail.com

If you have a girlfriend then impress her that how much you love her by showing her name in mail id.
