Again, given that the actual majority of posts to that forum are wrongly posted, surely it appears it 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 have suggested "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 posts have so frequently to be moved, it is apparently a waste of time suggesting it be corrected, because the forum maintainers have no intention of doing anything, do they?
