If you want a - somewhat closed - discussion among a few members - this is what the PMs are for - otherwise it quickly gets noisy 
just look at this thread because there is always another opinion.
A PM is the same as the any other forum thread but is limited to invited members.
There is a few members which often use education as part of the comments.
Others use the Tutorials section and write guides. The intent of such guides is to be referenced - to avoid answering the same or alike question again and again.
Improving is always good - but 99% of the packages distributed by Manjaro Linux is inherited from upstream Arch Linux and those are never changed.
