No I have not written a fourth edition, though I could easily increase the technical contant by double, with the experiance gaine in the past 13 years since the third edition was written.
We have just had the third edition reprinted with a very durable spiral binding, which we believe will make readers happy, as the book is used by all as a text/ reference book.
If you have questions which it doesn't answer to your complete satisfaction, I 'm hoping this forum will allow me to transfer my newest knowledge to all who have access to the site. You'll find my answers quite detailed and universal. Also, I will edit the questions at times, to attract more readers when my answers will cover a far broader scope than the questioner intended.
