What's a stub?
Stubs are articles that are very short, and are meant to be expanded upon. Think of them as placeholders until someone can expand on them. A good stub describes what the article might include, or perhaps gives links to include in the full article. It's a good idea to create a stub after creating a red link in an article.
How can I make one?
All you have to mark an article as a stub is add this text with the edit button:
This will mark the article as a stub, and add it to this page
Having stubs included in this page gives eager contributors a centralized place to find things that need to be done.
Here's a good stub example.
