From the developer:
Do you hate trying to remember how to format text in Wikipedia? Do you have a bunch of Word documents that you'd like to convert to use in Wikipedia (or another site that uses the same wiki engine - aka "MediaWiki")? This .NET/VSTO add-in for Microsoft Word will allow you to take a document authored in Word and upload it (with automatic format conversion) to Wikipedia, or any other site that uses the MediaWiki engine.
