A stub is a short article that need plenty of attention. If you see or find a stub, add to the article! Do some research on the article (perhaps using Google ;), take some notes on the article, and add the new information to the article. If you'd like to find some stubs to expand, go search through and see there. If you find a stub, enter {{stub}} into an article. Or better yet, if you find a stub, just expand to it! It's that simple.
