@Parlo
I think I understand what you're suggesting.
I'm a Staff member on H-M but I'm not the final word on your suggestion.
Regardless, following are my thoughts on it.
I think the crux of is here:
"So, in an ideal situation could an honest thread or forum be started
which is overseen by us all, where enhancements to posts would be welcomed and
dubious content highlighted and possibly removed?"
"To keep the standard of the posts high and to respect the sacrifices formally apprenticed machinists endured,
I suggest that only time served tradespeople can contribute."
I'm not clear by the meaning of "overseen" and who is "us all"? Please elucidate.
In short, I think you're asking for a thread or sub-forum where everybody can view the content but only specific members (authorized by you?) can contribute content.
The Admins will have to weigh in on whether or not the software supports that. To continue the discussion, lets assume the concept can be implemented.
The idea of removing dubious content is, IMO, a ball of snakes that should be avoided.
After all, this is the internet. It's up to the viewer to decide what content is valuable to them.
Alternatively, please comment on why you don't simply do what the other contributors do by creating a thread (in either the Projects Area or in this forum) which shows what you're trying to teach. I acknowledge that such a thread can become cluttered with congratulatory, alternative or off topic replies. Is it that clutter that you are specifically trying to avoid? I suppose a thread could be locked, at the request of the author, to prevent the common clutter/drift.
IMO, members, who post their projects, develop a reputation as to the characteristics of their techniques and output. Good, bad or indifferent.
For that matter, each of our posts (comment, project, purchase, whatever) serves as a data point in creating our individual credibility and reputation on H-M. You've been a member for ten months and I expect you have developed opinions about some members activities. If you post your tutorials, regardless of using the normal manor or a special forum, each viewer will decide what is valuable or not.
I would welcome input from the Admins and other Moderators.
I'm tired, Goodnight.
