I just posted an unique opportunity for authors on my Sharing with Writers blog. It's a Book Pavilion at a Green Expo. The package for table (booth) and video interview that will keep you promoting your book for a long time in the future to everyone all over the world (well, anyone who is connected to the Web)is under $300. I will be hosting. I'm more than a little excited about this!
And know that you are green. If you do green stuff in your office, you're green. If you publish on recycled paper, you're green. E-books? Green. Kindle or other readers? Green. Yes, you can make this work for you. Or just pronounce your commitment to green and you're on your way.
