Mark, sorry for the resend, I forgot to reply-to-all.

You're missing one superclass.  I wish IB were smart enough to search  
a source tree and find the classes it needs...
GaimQQJoinChatViewController : DCJoinChatViewController : AIObject :  
NSObject

DCJoinChatViewController and its subclasses don't actually control a  
window, so it's not an NSWindowController subclass -- it configures a  
view which is within a window, so it's just a standard object. An  
AIObject, in this case (which is what most objects in Adium inherit  
from -- it allows easy access to the 'adium' instance variable).

Your eye probably jumped to DCJoinChatWindowController which has a  
similar name.. it manages the entire window.

The group chat stuff is fairly old at this point and is a little  
convoluted, though quite functional. It is in need of actual  
documentation -- sorry for throwing you into the lion's den :)

With the theoretical out of the way, the practical:
Read Files... select AIObject.h from Adium Framework/Source.  Then  
read DCJoinChatViewController.  (You can also drag the .h file to the  
document window in Interface Builder... that's what I usually do).

Did that help?  Let  me know if any of that explanation was unclear :)

Cheers,
Evan

p.s. Import Resource is basically useless.. it's for if you want to  
imbed a sound file, a picture, etc., in the nib bundle... which is  
considered a deprecated thing to do by Apple and is therefore not  
recommended in the first place.
