After going through faq and seeing questions http://meta.blender.stackexchange.com/questions/29/what-would-be-wrong-with-tutorials-as-long-as-they-describe-a-reusable-workflow and http://meta.blender.stackexchange.com/questions/1/what-questions-should-be-definitely-off-topic
Two points are fairly clear:
- The site isn't a ground for tutorials
- People are going to come by asking for them
To help out on that, and to help more experienced users who still have what to learn, I propose building a page where links to documentation, references and tutorial are available. This would also make the site more welcoming, instead of just closing the question.
Another option, just linking to http://www.blender.org/education-help/
