I would probably use actionscript at the end of your flash intro. 10 sec delay is good only for people with high-speed connection. but if somebody has to wait for the intro to load they may miss the end part b.c. 10 sec will elapse before the animation finishes. and also, "skip intro" is also a good idea. options are always good :)

so the code that you would put on the last frame of your flash animation would be this:

----------
stop();
getURL("homepage.html");
----------

and your skip button's code would look like this:

-------------
on (release) {
getURL("mypage.html");
}
--------------

hope this helps.
