@user334732 I totally agree and I think it could be very useful for the comunity! Ok let work togheter for that!
I already exhort always new contributors to improve their answer and sometimes they react very well. Here is an example for a great result obtained today.
At first the asker presented only a short answer but after a guide he succeed to solve the entire question by himself and add his work editing the question.
So I think that we need to follow the "New Contributor" policy more closely to involve them in a proper way. Suddenly closure and deletion are clearly totally ineffective!
I also was thinking to create a similr chat room! :)
