Following Add-in allows you to use Microsoft Word to edit an wiki page offline.
You use the normal Word bold, italic and tables features to create the Word document.
When done just choose File –> Save As and select MediaWiki* under file types.
Word will now convert and save the document in Wiki style markup.
You then just paste the contents onto the wiki editor box.

Hopefully with this, it make creating pages on the wiki easier.
