Have anyone noticed that the reason why some persons post go off the topic is because they don't read the entire op writing before they reply to a thread, some persons respond to a thread based on the caution of the topic and that is why we meet up different opinions or suggestions that is not in lines what the OP points of view.
Secondly, when someone have written what you want to write in same thread you have to give off, instead of making a pointless point, I know very well that many users in forum make off topic because what I outlined.
Normally is very necessary for us to always read the rules and regulations of any thread before we make any comments because reading it very well is going to help you to know the right word to use and make your comment, although why must people always make off topic is because they didn't want to settle down and go through I thread very well before them respond, they are just after to complete their post, that is why must of us keep on making this mistake.
