Preloader

Hi,

I have created a preloader that takes up two frames. I now want to implement it into my main page. do I need to add it to the two frame in my main page or can I covert the whole lot into a movie clip and place it into one frame.

My main problem is trying to keep my scene and times line nice a clean so I can come back to it later adn know what is what.

can anyone give me some tips as well on management in flash?
