Google is now offering its offline Gmail system to enable email users to carry on working on their webmail even when they don't have an internet connection.

Google said, "Once you turn on this feature, Gmail uses Gears technology to download a local cache of your mail. As long as you're connected to the network, that cache is synchronised with Gmail's servers.
"When you lose your connection, Gmail automatically switches to offline mode, and uses the data stored on your computer's hard drive instead of the information sent across the network. You can read messages, star and label them, and do all of the things you're used to doing while reading your webmail online."
Any messages "sent" while offline will be placed in the outbox and automatically sent the next time Gmail detects a connection.
"Our goal is to provide nearly the same browser-based Gmail experience whether you're using the data cached on your computer or talking directly to the server," said Google.
Offline Gmail is available to anyone using Gmail in US or UK English.
