Again, restricting the forum would mean not having to move them or close them. As for noobs being noobs, I think preventing posts in the tutorials section would help. If new users actually go looking for the right place for their question then they might see within that forum that their questions has already been asked rather than just posting in the tutorial section.
Yes and no, take my
thread for example, it's there to make life easier by making sure every single helpful thread out there is in one nice little place. It's made to be asked questions on and post threads in reply, then the threads get added to the thread. Basically, made to eliminate the need to search or look very heard to find the best threads and it was even stickied to make thing things even easier. There is also 3DS NOOB PARADISE, which is made to ask all your questions without judgement.
You would think being provided with these kinds of threads, that it would slow down the large quantities of questions that these threads cover, but the the truth is, they really haven't made that big an impact. They do help those who go to them to get the help, but for the most part, people just ignore them.
This isn't a GBATemp exclusive issue, going to any forums, you find these kinds of things happening as well.
Although, it would be nice to see something like, "You need 100 posts," to post in these threads. I am not entirely confident it will fix the problem completely.
Then again, I could easily be wrong. Personally, I don't object to the idea, I am just a skeptical person.
