If for yourself, then none of this should matter. Show it to whoever comes upon it.
If for people here @ a-m-v.org , then post it once in the AMV Announcements, do opinion ops (though I am personally against that, seeing as most opinions seem to be rather pointless), and pimp in the IRC chat.

Want to know the secret of how to become better known no matter which one you choose? Make it good. And by good I don't mean average. I mean make it excellently edited and superbly synched. Make sure the audio is catchy and the video is known.

"If you build it (good), they will come" .
I can't remember what that was from, but I know its famous, or something.
