Hey fallz19,
A good place to start would be to check out this site's
AMV Contest Calendar to see what contests are coming up soon. When you find one you want to enter, go to the contest's website (this should be linked from the calendar) and look through all the rules and requirements, which should also give you the specifics of what you have to do to enter (every contest will be different).
Another great resource is the very board where you posted this thread, the
AMV Contests board. It seems that many contests are only posted in one or the other, at least at first.
I can tell you right now that it does NOT suffice to go to the "Cons" page of your video information and start checking conventions left and right. That mechanism does not actually get you entered into any contests -- it's there when you want to indicate that you
already have entered.
I hope this helps. Thanks again and have fun!! ^_^

I'm really beginning to wonder how many people are left who still get the joke when I do a post in this style.
