Wow. The reason why I asked about publishing a book in the "ask a teacher" section was because I wanted to ask a teacher. I don't know of any teachers who have actually published a textbook. I was looking for a teacher who had gone through the process. I understand that there are a lot of sites about tips, but I wanted first hand knowledge. I'm sorry about taking up the space. I thought I was in the "ask a teacher" section, not the "language" section.
Again, I apologize.
