SEVENTH EDITION! That's phenomenal - congrats on an awesome achievement.
Sorry, got carried away by your book - now, back to business:
As I say, "Welcome!"
This is an awesome site for even authors of seven-times-published award-winning books, so you will fit right in! Go over the various pages (Teller Pages, Video, audio, Photos, Forums, Groups, etc.), take your time, get involved, ask questions, answer some, make comments, share with us a bit of what you know, and grow along with the rest of us.
I look forward to our receiving your input and counsel on the site, I am delighted you are here with us, I look forward, personally, to becoming familiar w/ you and your work and, again, I offer you my sincere Welcome!
