Guess what the power users of Wikipedia use to edit...
TheAutoWikiBrowser (AWB), of course.
AWB is a semi-automatic Wikipedia editor. It works on lists (batches) of pages, automatically edits the first page the way you specify, and then takes you to the next page once you approve the changes to the current page. It has powerful features. It can even run an externalscript,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 Wikipediaadministrator.
AWB is very useful and helps perform repetitiveWikiGnome tasks very quickly, likestubs sorting, substituting templates, and searching/replacing.
