The JRuby Community
JRuby has a large and active community. You can connect up with them in several ways:
Blogs - The JRuby Team, individual team members, and a number of folks from the community blog about JRuby and related topics.
Twitter - There are twitter accounts for The JRuby Team and all the team members.
IRC - Many members of the JRuby community can be found on IRC, on the FreeNode network in the #jruby channel. Most of the core JRuby developers also communicate on IRC. If you want quick, interactive help or just want to hang out, feel free to stop by!
Mailing Lists - There are also several mailing lists, for users, developers, and folks interested in tracking the process of JRuby.
Bug Tracker - Users are encouraged to report any bug, however insignificant it may seem. Please run a couple searches first to see if your bug has been reported, or ask us about it on IRC or the mailing lists.
Wiki - The JRuby wiki–user editable.
