To forward quest status in Jamba:

Go to the addon interface options for Jamba-Talk.

Click the "Options" tab.

Check "Forward UI Information".

There is also a forward UI errors options as well; but I don't think you need that. You will get other messages as well; I'm adding a filter to Jamba 0.5, so you can forward only the messages you are interested in.

(Make sure you are using the latest version of Jamba.)
