The only catch is that you have to use AutoCAD for 20hours a week :-)
"Autodesk Research is continuously investigating revolutionary ways to further enhance Autodesk products. We are currently performing a study and seeking AutoCAD 2009 users to assist us in our efforts. Volunteers must use AutoCAD 2009 (or one of the domain specific verticals) at least 20 hrs/week.
Volunteers will be paid $100 in Amazon Gift Cards.
The study consists of the following components:
1) Run a short configuration script on your computer
This will take less than one minute and will have no visible effect on AutoCAD or your system. This script will allow us to collect information about which commands you use and when you use them. User names, company information, and underlying data are never transmitted.
2) Continue to use AutoCAD 2009
We will be collecting the command information over a period of approximately 2-3 months. This requires no action on your part; just continue to use AutoCAD 2009 as you normally do.
3) Complete a post-study questionnaire
The questionnaire will be sent to you by email, and will take approximately one hour to complete. The survey will ask you questions about your like and dislike of various AutoCAD 2009 commands.
Volunteers will be paid $50 upon signing up, and $50 upon the completion of the study.
