If you know what .docx is you probably are using the new Word 2007 program. There's no .docx files on my PC yet! I'll be honest with you... I am still living in the dark ages and using an older version of Word, as most of you probably are.

One reason I have yet to take the plunge and buy Word 2007 is that it's interface is quite different than its' predecessors. -how about you?
You may be in luck. Tutorials have started showing up on the net that will help you, should you ever decide to take that plunge.

I found this site where, the tutorials are terrific, they cover the new Word program and more. Some are free and there's also a fairly inexpensive subscription program that they offer. I think it's well worth giving it a try..
