The first experience for new users to the English Wikipedia
How would new users know to go to the New Articles Noticeboard while they're working on their first article? Would we just force every first article to be created in userspace and moved into mainspace only by an experienced user who has worked with the new user? It seems workable, but not everyone would agree that it's a good idea.
What if we created such a noticeboard, but didn't force people to go to it, instead just strongly suggesting they go to it when they create their first article? (And, if they didn't go to it, suggest again when the article gets deleted and, as above, moved into userspace.)
I'm sure a template could be created that notifies new users, when they try to create a new article, that they can/should/must start in their user space first. Guidance and instruction is desperately needed for new users, otherwise they will continue to be frustrated by the complexities of Wikipedia, usually never to return. Whether it's required, or suggested (with help in doing it), something has to be done to help new users who create articles from being permanently frustrated by Wikipedia.
