AS3.0, Sprite, FP9 .fla's and so on

Ok, let me get the suggestion out of the way. Are there any plans for a AS3.0 section to the forum? It would be really nice to start lumping all the AS3.0 stuff together. Just a suggestion.

Ok I have two questions:

#1. Anyone know how to instantiate a subclass of flash.display.Sprite WITHOUT implementing the iUIComponent interface in Flex 2?
From what I have seen with say senoc’s AS3 tip o’the day and others, it seems you are extending the Sprite classes then using the addChild method. That doesn’t seem to work in Flex 2 since the addChild’s first parameter, even though a DisplayObject, is required to implement the iUIComponent interface. This may be unique to compiling in FB2 though.
**
#2. Can someone briefly explain to me how some of you are compiling flash player 9 swf’s using a fla and AS3.0 classes?
**I have been really stuck using the Flex 1.5 & 2 IDE’s lately and am out of the loop on this topic. Doing this might just solve question #1.

Thanks folks.
