If you don't feel ready to fix the article yourself, please post a message on the article's talk page. This will bring the matter to the attention of others who work on that article. There is a "Talk" link at the beginning of every article page.
If searching Wikipedia has not answered your question (for example, questions like "Which country has the world's largest fishing fleet?"), try the Reference Desk. Volunteers there will attempt to answer your questions on any topic, or point you towards the information you need.
AWB is a semi-automatic Wikipedia editor. It works on lists of pages, automatically edits each page the way you specify, and then automatically takes you to the next page once you approve the changes to the current page. It has powerful features. It can even run an external script, regex (regular expression) on each page it processes.
In order to use AWB, you must either be an experienced editor with over 500 edits, or a Wikipedia administrator.
AWB is very useful and helps perform repetitive WikiGnome tasks very quickly, like stubs sorting, substituting templates, and searching/replacing.
