Check it out,
.Mac subscribers: In the "Members Only" folder of your iDisk (that still makes me think of the jackets),
you'll find two chapters of Joe Kissell's book, Take Control of .Mac.The first chapter focuses on using Mail,
and is extremely thorough. Discussions include making use of aliases, .Mac webmail vs. an email client, working with
attachments and configuring the online preferences.
Chapter 2 looks at Groups, a relatively new .Mac feature. Topics include creating a group, managing your members, adding content to your homepage and working with the integrated calendar. Again, I found them very informative, and the best part is that you can use a hyperlink within the PDF itself to get the full book at a 30% discount. This one is recommended.
