Having trouble remembering wiki-markup?  Well, here to help you is the Sun Wiki Publisher extension for OpenOffice, the open source productivity suite.  The extension allows you to use all of OpenOffice's formatting tools (bold, italic, tables etc.) and simply upload the page with "Send - MediaWiki server". The extension works with any MediaWiki (e.g. Wikipedia) based wiki and requires StarOffice 8 (Update 10 or higher) or OpenOffice.org (2.4 or higher). [Sun Wiki Publisher via Lifehacker via Linux.com]
