Internet Connectivity has become a lifeline of people around. So what happens when you are checking the Mail and then suddenly is it get’s disconnected then? How will you read the mail you were reading?
Google Has managed to find out a great solution. All you need to download is Google Gears.
It works like this – Whenever you are connected to the internet your
mail is Updated but as soon as you loose the connection Gmail will auotmatically switch to offline Mode. You can do everthing in that Browser just like how you used to do it when you were online Mark Mail, Read mailm label them. All this works as Gmail Stores the Data on your Hard drive. You can even Compose a Mail, it gets stored in the outbox and will be sent as soon as you connect with the Mail server. Like it? I love it. We need this in India especially as there is no guarentee about your internet connection. Thanks Google!

But also Please do not sign up with that email because if once the Virtual Email id vanished you will never get the emails sent to that, so use this for only when you just need on email to activate something.Using things like this is something called smartness because you are using a shield to protect your self from being spammed. Yeah! We found it!
