I've given a lot of writing workshops over the years, and have posted most of the slide presentations on Slideshare, where they're free to view and download.
Four of these workshops were given at the Sleuthfest mystery convention in Boca Raton, Florida, and audio recordings of those workshops are available for purchase as MP3 or CD. They follow the slide presentations saved on Slideshare, so if you download the presentation (for free) and purchase the audio recording, you'll get the experience of the workshop.
Please go to vwtapes.com and type "Vincent O'Neil" into the Search box to see the audio recordings.
Here are the slideshows available for free on Slideshare:
