Main.asc...where to start?

Hi all...

Firstly excuse my complete incompent knowledge before hand, I am am pretty amazed I got as far as I did already

Now the question...I have developed a videochat application in Actionscript 3, basically, a user registers can broadcast up to 3 various cams and site visitors can view and discuss.

What is the procedure of developing the main.asc file for this script? What are the main points that I would have to include for it to function?

Again, my apologies but I am still new born in the developing script world.

Regards!!
