    I accept and advise from you,but in my opinion focusing in one topic may not be the correct action because this topic may not be interested for all, I try to work on many topics to get all Visitors be satisfied.
    just follow day by day and you will find new topics in different fields that be suitable for all visitors.

  2. Hi Sir Ali can you please continue the topic from letter D.Basic law of sound up to 11. Dictionary of sound system. Thanks a lot this is very useful reference
