"Windows XP Inside Out." 

But seriously, folks...if you're going to stick with ME, here's about the best book you'll find on the subject:

http://www.amazon.com/exec/obidos/ASIN/059600009X/qid=1077688585/sr=2-1/ref=sr_2_1/103-6637316-3543028

On the other hand, if you have the hardware for it, XP is a much, much better operating system.

Another in-depth reference (which can be purchased used for a reasonable price) is here.

The book I chose is by Ed Bott. "Special Edition Using Microsoft Windows Me" ISBN 0-7897-2446-4. The price on the book cover is $39.99. Probably can get it much cheaper now. Try Amazon or Barnes & Noble.

...and the ever popular Do It Yourself Windows ME by Bjoern-Erik Hartsfvang. For step-by-step instructions if you're looking for something like that.

Thanks for all the suggestions.
