Have a question that you can't find answer to in the documentation? Here are some additional resources for help:
The netscape.public.mozilla.jseng newsgroup answers questions about both Rhino and the C implementation of JavaScript. You can get to the newsgroup through a mail gateway. Send a message with the subject "subscribe" to mozilla-jseng-request@mozilla.org. To post messages, send mail to mozilla-jseng@mozilla.org. To unsubscribe, mail with "unsubscribe" in the subject to mozilla-jseng-request@mozilla.org.
To view archived messages, try Google groups or other newsgroup services.
Use Bugzilla to enter bugs against Rhino. Note that Rhino has its own product category.
The module owner, , can be mailed for help as well, although he may copy his response to the newsgroup to help others.
