Mostly. We took JForum 2.1.8 and forked it to add our own features and remove some features we don't use. You know techies. Can't leave well enough alone. More information about what we added and changed can be found at ReadingAboutRanchJForum.
Is this forum about pure JForum or Ranch JForum
Is the the Ranch JForum fork available?
No. At least for the time being, we have decided to keep our fork internal. We are happy to talk about the features in this forum upon request. A number of the features we added have found their way into the JForum fork at GoogleCode, though.
