Again, if you're going to do it, you may as well do it right. If English is not your primary language, then you could ask your English-speaking friends for input and suggestions for improvement. If you're new to producing tutorials, then you can use this as a learning experience. Invite constructive feedback, then go back and improve your product. People can show their gratitude, but still want something that does the job. I'm looking for something that works. I already tried some stuff, and it didn't work. I don't want someone sending me back to the stuff I already tried.
