As with any open discussion forum, quite often topics will re-appear from time to time, and we welcome that. Otherwise, we'd wind up with a finite number of posts, and eventually we would have nothing further to talk about. And, as mentioned by Glasslass, it's always beneficial for the newbies to re-visit topics.
If you feel that a topic is redundant or not necessary, please feel free to move on to another thread which you may feel worthwhile.
You don't have to agree with each other.
You don't have to even like each other.
But please, respect each other.
