Really enjoying the Self Publishing School's webinar series, which just started today. Ten days worth of videos, free if you watch them within three days! I'm learning a lot and just watched the first-day webinars from Taylor Pearson, Claire Diaz-Ortiz and Ray Edwards.
The seminar is free but they encourage you to sign up for a $400 pass to see the videos whenever you want. I'm just watching them day-of -- it's cheaper!
