Advanced JavaScript discussion forums?

I posted a query about best practice in concatenating JavaScript files here http://www.codingforums.com/showthread.php?t=139216. But then from looking around I realised this probably isn't the most appropriate forum to post this type of question in.

Does anyone know of any popular advanced JavaScript forums where I can discuss things like best practice in object oriented programming and setting up JavaScript frameworks etc.?

Ta,
Robin.

i dont know any 'advance javascript' forums.
but i know that webdeveloper.com has some really
good knowledgable people on there

several guys who have written books on javascript / ajax on there
many with 1000 ++ post
