Gmail helps you stay in touch in a variety of ways. Its offerings range from its basic function email to more advanced features such as phone calls and video chatting. To send an email or chat via text on Gmail, you don't need to do anything more than create an account. Before you can start video chatting with your Gmail contacts, however, you must install the required software.

Visit the Google Voice installation page (link below). http://www.google.com/chat/video Click the blue "Install voice and video chat" button. When the process is complete, you see a page congratulating you on installing Google voice and video chat. Click the "Gmail" link on this page to go to your Gmail account. Hover your mouse over an online Gmail contact in your contact list. Click "Chat" in the list that appears. This opens a chat with the contact in question in the lower right corner of your Gmail screen. Click the small video camera icon within the chat window to initiate a video chat. Before the chat begins, your contact must accept the video call. You and the person you're calling must have webcams. Most modern laptops come with built-in webcams, and peripheral webcams are available at computer stores.

Click Start/Control Panel/Hardware and Sound/Sound/Sounds and scroll down and select new mail notification. Highlight New mail notification and click Test, then click OK.

Also check you email client (the program you use the get your emails (aol, yahoo, gmail, etc.) and see if they have settings in them for notifications, most do.

Check the software you use to get text messages for settings on notifications to get sounds or alerts when a text message comes.

It sounds like your charter account is configured to forward all of your email to gmail. If you cannot change this yourself, contact charter and ask them to remove the forwarding rule.

Good luck

ITS A SCAM BY A GROUP OF MOTHER ******* BEAWARE OF THIS EMAIL FRAUD
Lottery scam is a type of advance-fee fraud which begins with an
unexpected email notification that "You have won!" a large sum of
money in a lottery. The recipient of the message - the target of the
scam - is usually told to keep the notice secret, "due to a mix-up in
some of the names and numbers," and to contact a "claims agent." After
contacting the agent, the target of the scam will be asked to pay
"processing fees" or "transfer charges" so that the winnings can be
distributed, but will never receive any lottery payment.[1] Many email
lottery scams use the names of legitimate lottery organizations or
other legitimate corporations/companies, but this does not mean the
legitimate organizations are in any way involved with the scams.

There are several ways to recognize a fake lottery email:

Unless someone has bought a ticket, they cannot have won a prize.
There are no such things as "email" draws or any other lottery where
"no tickets were sold". This is simply another invention by the
scammer to make the victim believe that they have won.
The scammer will ask the victim to pay a fee before they can receive
their prize. It is illegal for a real lottery to charge any sort of
fee. It does not matter what they say this fee is for (courier
charges, bank charges, various imaginary certificates - these are all
made up by the scammer to get money out of their victim). All real
lotteries subtract any fee and tax from the prize.
Scam lottery emails will nearly always come from free email accounts
such as Yahoo!, Hotmail, Live, MSN, Gmail etc.

What mail service do you use? If you use Gmail, install Google Talk or if Yahoo, use yahoo messenger and for hotmail use live messenger.
