I want to check/study the source of this plugin, but I'm unable to find its source. I assume it's opensource, as the main class is com.jivesoftware.spelling.SpellingPlugin, indicating it's part of jivesoftware.
I downloaded the latest spark source, and also browsed the svn repo. Found source for some plugins, such as jingle.jar, but not the one I wanted. If you know where it is, please let me know, thanks a lot.
