It appears that forum seriously needs to be meaningfully re-named. People are clearly not inclined to read the About the Installation & Troubleshooting category description any more than how to use this forum.
I suggest "Installing/ Troubleshooting the Arduino IDE", because according to the "about", that is what is is intended to be, but it needs to be up front. 
But even though this same situation comes up again and again and again with posts having to be moved, possibly even the majority of posts to that actual forum, it is a waste of time suggesting it be corrected, isn't it?
