Essentially, this forum is an agregator for RSS feeds. This is a way of monitoring useful blogs, articles and knowledge bases across the web so that when a new article is posted on any of them, a new thread will appear here to keep everyone informed. Currently we are subscribed to:

The Autodesk AutoCAD Knowledge Base
Between the Lines - blog by Shaan Hurley (Autodesk)
CAD Panacea - blog by R.K.McSwain

HyperPics: Beyond the UI - blog by Lee Ambrosius
Lynn Allen's Blog - blog by Lynn Allen (Autodesk)
AutoCAD Tips Blog - blog by Ellen Finkelstein
