If you've been looking for a good way to learn about writing white papers, you'll find a great resource in the teleclass Fundamentals of White Paper Writing, led by Michael Stelzner, a well-known author and white paper writer.
This class is the first in a three-part series: July's class will cover white paper elements and in August Mike will discuss advanced writing techniques. When you sign up for all three classes at the same time, you can get a great price of just $69 (a combined $87 value; other bundle options are also available).
The first live class will be held on June 21, 2007, but you can also order the audio file later.
