Well, actually that's not entirely true. But I won't go into the details of posting it all here.
Sure, if a new user comes in and has questions like 'how do I use the mic?' or whatever, then of course any other user is welcome to explain - that should just be part of being friendly and welcoming.
But making a team of people responsible for 'technical issues' many of which aren't that simple, and need in depth knowledge of the site- well that's not a viable option- as I have already explained.
