There are Microsoft Technet forums, Answers and Tech Community
of course the TechNet's educating contents are moving to Microsoft Docs but the forums still exist.
Why not bring all these 3 sites under 1 unified roof?
I have 2 ideas:
1. merge these 3 websites into one place to find answers. if I have a question, I don't know where to post, TechNet, Answers or Tech community. maybe all 3 places? then keep track of 3 websites to see which one gets an answer first? that's not convenient at all.
2. merge the user profiles of these 3 websites so a user will create only one profile and then he/she will be able to use it on all 3 websites.
