Hi ,
No , it does not mean that.
What it means is that if you post your question in more than one forum , then post links to all the forums where you have posted your question in every forum.
Thus , if you have posted your question in forums A , B and C , in forum A where you have posted your question , mention that you have also posted your question in forums B and C and provide links to those forum posts ; in forum B where you have posted your question , mention that you have also posted your question in forums A and C and provide links to those forum posts ; in forum C where you have posted your question , mention that you have also posted your question in forums A and B and provide links to those forum posts.
That is all.
And as when you get a proper solution to your question from any one forum , immediately post that information to all the other forums where you posted your question.
