Yellow Card is a WordPress plugin that lets blog visitors flag objectionable comments, and reduces the visibility of comments that have been flagged a certain number of times. The number of flags required to reduce visibility and what constitutes reduced visibility are configurable, amongst other things.
Tested on WP 2.0 and 2.1, with PHP 4 and 5.
0.3 Original release, 5/1/07.
0.4 Added multiple flag types, 5/10/07
The current version of Yellow Card is available here.
Yellow Card is open source software, released under the MIT license.
YellowCard was inspired by an exchange of comments on a blog post by Tim O'Reilly. It's based on functionality from http://www.librarything.com and Craigslist. It was built by me, John McGrath, in May 2007.
Suggestions welcome. If you want to translate Yellow Card, write me: john[at]wordie.org.
They're totally unrelated, but you might want to check some of the other stuff I've built, like Squirl and Wordie. Especially Wordie, which is awesome.
