Seriously, I can understand where you're coming from. Try my view. This forum is meant to be a place where people can learn more about advanced C/C++ development in a place where spam and trolling is not welcome.
Opening up these forums would honestly work only under two conditions: more moderators doing very strict moderation, and more people actually willing to write documentation instead of just more people requesting installation support.
If you can tell me how we can keep the forum quality as good as it is with all those friendly, and kind people we have here, even with a few thousand more users, then make a suggestion, give a helping hand, and we can try it.
It's not that I am unwilling to open things up, I just prefer suggestions that come with possible solutions
