Gmail, E-mail provided by Google, has become all the rage nowadays. Everyone is talking about its ease of use and its seemingly unlimited amount of space. But, there is one important thing to consider when setting up your Gmail account; you need to import your existing E-mail addresses from whatever email account you're using now.
Luckily, Gmail makes this pretty straightforward. All you need is a CVS (.cvs/comma delimited) file. You can create these by exporting your existing address book into a CVS file.
These files have fairly simple fields: name, E-mail address, etc. You can add additional fields like address and phone number, but Gmail may just throw this into the notes field. So, just name and E-mail address seems to be preferable.
