Nice resource for lawyers:  MentorCLE offers free on-line courses on legal subjects for Illinois lawyers. Included is this course on Persuasive Writing For Lawyers by Helen Gunnarsson. You can pay $19.95 to convert your time into an hour of CLE credit.

There is a list of a number of great presentations on the site here. Got 15 minutes and a cup of coffee? Why not learn something new? Great job, MentorCLE!
