Some tips

You only have to type the squiggle-line-word in once, to verify that you are a real person; you'll never see it again.

Labels
Labels are like folders, only better. Create labels to separate email into easy-to-manage groups. The best part is an email can have multiple labels. You can have the system automatically label incoming messages, to do this click on "Settings" then "Filters".

Archive
When you label messages you will still see them in your Inbox until you archive the message. Just think of the archive button as meaning "remove the 'Inbox' label from a message".

Notifications
Use the Email Notification Add-on for the Firefox web browser. Download, install, put your email@up.net and password in and you can instantly check your email when surfing.

Want to change how your name displays?
Go to "Settings --> Accounts --> Edit info" to change your name. (Note: this is to change "Robert Jones" to "Bob Jones", not to change your email address)
