Then I fail to see how this unfairly affects you or other forum members.
If it is possible to simply gloss over such threads and move on, what's the big deal?
Have they become frequent enough where they consume your forum experience? Do you dread browsing those forums?
Do they prevent you from seeing other threads you might be interested in (I hope you answer "yes" to this one, as it's on my list as well)?
I subscribe to the view that if you teach people early in their forum life, about appropriate actions on said forum, that they will take these lessons on board and will learn. That will translate to the majority of other board users in good time. There's no overnight fix, or something that can solve it immediately.
I don't disagree with such a philosophy, I merely question the ability of this particular idea to deliver the desired results.
It wouldn't be appropriate for us to take up this idea simply because no other idea has come forth. We'll just have to go back to our thinking caps and try, try again.
Sarcasm. Sarcasm smilie for future reference -->
No sarcasm was intended. I really do appreciate the mods, and I try to make their lives easier by reporting posts and following the rules.
I believe some form that we've been over is appropriate. It may turn out it's not ideal to be introduced as a Newbie Forum...
Please describe one incarnation you feel would work, and I'll be sure to demonstrate why it doesn't.

Obviously it's not "throughly hashed out", which is why we're talking about it.
I wasn't aware zealous advocacy=talking about it.
You need to understand that it is not my intention to alienate other members, or to drive any away, but rather to suggest ways to weed out the unnecessary threads - and you've got to admit they're just that.
I'm afraid though, that any plan which separates by post count will end up creating alienation. It works when you're only restricted from a handful of forums, but when the vast majority of the forums are off limits to you, then you're not going to feel that the site is very neighborly.
So what if it's small potatoes? They're still rotten potatoes you shouldn't put in the oven along with your Sunday Roast.
The reason we should consider if they're small potatoes or not is because if the problem isn't too grave, then any solution could potentially do more harm than good.
There is no panacea for forums. Fixing one problem invariably reduces usability or ease of use, or some other facet of the forum. As such, it's best to only fix things when they are in serious need of repair.
I haven't yet been convinced that this problem is large enough where it requires a change as drastic as creating a new forum, separating members, and changing the entire new member experience.
Have you ever used a forum that had this implemented before? I've mentioned several times in this thread that I have, and it works.
No, I haven't. I'd love if you were to link me to a few of them.
Again, it's a good idea - I use another forum which is roughly the same size as this, and their new member policy is that new threads need to be moderator approved first.
That isn't the same as the "sandbox" you suggested earlier.
The moderator-approved method, I agree, will always reduce the number of repetitive threads to nearly 0. However, it requires a massive time investment on the part of more moderators who aren't paid anything.
Asking moderators to do this would be a bit much no? At the very least it would require doubling the moderator force in order to meet the possible demands of new users.
So you don't agree with a thread? Why are you posting here then?
Disagree with substance and not wanting to participate in a settled discussion are two very different things.
Do you deny that it'd improve the forums if we didn't have duplicate threads, flaming wars, and other annoyances that, unfortunately, are mostly caused by newer members?
I don't think anyone denies that. The only question is what (if anything) can be done to stop it. That is the million dollar question.
