Where to get support, how to help yourself...
For general ChatZilla questions, read the ChatZilla FAQ. If the FAQ does not help, you can try asking in #chatzilla on moznet.
Don't ask for support in Bugzilla, Hendrix, or Mozilla Add-ons comments. It really won't help.
Also note that I don't know of any ChatZilla developers that actively read MozillaZine forums, so I wouldn't bet on getting answers to obscure questions there either.
If your question is specifically about the plugins and packages on this site, please remember that these are not officially supported.
Others in #chatzilla may be able to answer your question, but if in doubt, address it to me (tH) or see my personal contact page.
