Tips and Tricks Contest - Win a great book!

Thanks to the generosity of James Wedding, Ellen Finkelstein and Rick Graham, I have some very sweet prizes for three lucky readers!

I've linked to the table of contents of each of these wonderful texts, check out everything these authors cover. I haven't read Mastering Civil 3D, as that's not my industry, and I don't own a Mac but, I'm sure those books are just as chock full of tasty tips and will serve as a handy reference just like the AutoCAD Bible (which I have read in the past and do highly recommend).

Contest Rules: 

1. Post a tip about any Autodesk product using the comments area below.
2. Tell me which book you'd like to win.
3. Provide your email, so I may contact you for your mailing address if you've been selected.
4. Contest is open until March 18th, 2011. 

The winner will be chosen at random by my two-year-old.

I apologize, but, the winner needs to be in the United States (these are pretty heavy books and I'll be footing the bill for shipping), unless you're willing to wait for a hand-delivery at Autodesk University 2011?

Since I now have moderated comments (due to having far more SPAM comments than real ones), I will be collecting the information posted there, but, will not be publishing the comments themselves.

The tips and tricks submitted by the contest entrants will be shared in a blog post the last week of March.

Use the following as a guide to submit your tip:

Name: Melanie Perry

Email address: mistressofthedorkness@gmail.com
Book Preference:  AutoCAD Bible
*Attribution*: Melanie "Mistress of the Dorkness" Perry

*Product*: AutoCAD

*Tip*: Use the Express Tool "SYSVDLG" to access your system variables, and even save them as an SVF file to preserve or share your current settings.

I'll only be posting those fields marked with an asterisk, and of course, I'll only be using the email address you provide to contact you if you're the winner.

I am asking that you share a tip with me, in exchange for your chance to win a free book, but, it does not have to be restricted to AutoCAD or Civil3D, if you have a great Revit or AutoCAD MEP tip etc, feel free to share it.
