Once in a while, you may need to attach a file to your email message. Part 4 will mainly revolve around editing attachments and what buttons you got on the hotbar in the address book. By now you should be able to navigate fairly well in the Thunderbird user interface, so I'm going to give a few more pointers in this part than the previous :)
The first thing you need to do is open a new message.
Having done that, you need to press the attachment button, right next to the attachment button is there also an arrow; you've got 2 choices, either attach a file or a web address. Click on the attachment button, and a window for browsing your folders will appear for your hard drive.
Locate the file you want to attach from your local directory, and press open. Your mail message now has a file attached. If you want to add more attachments to the same email simply repeat the process. If you want to attach a web page, simply choose "Attach web page" and fill in the URL (for example http://www.mozilla.org).
This button will allow you to create a new card in your address book, a new card can be a friend, a business relation and so on.
This button will open a window where you can create a mailing
list. These lists are handy if you want to send emails to a group
of people, for example friends at the golf club.
Lets you edit the highlighted card in your address book.
Will open a new window for writing a message to the person highlighted in the address book.
The delete button will delete the highlighted card from your address book.
Hope you have enjoyed this part as much as I enjoyed writing it :)
