I'm sure many of you caught the news article(http://www.wired.com/wiredscience/2009/08/wikitrust/) about Adler and Alfaro's research(http://doi.acm.org/10.1145/1242572.1242608) in wiki trustability being applied to live Wikipedia. It just so happens that I have been working on a similar problem from a completely different direction during my research and am ready to share this work with the community. I have designed and implemented a user script modification that I call HAPPI and am currently running a non-profit/academic analysis of its usefulness. The script adds a couple of new controls that will appear over the edit pane. These controls will allow you to toggle the highlighting of wiki text while you edit it. If you'd like to give it a try, please see the documentation page and consent form for more information.
