So you've got a great machinima now. Most likely you will want to relase it to the public. You can do that through sites like YouTube (http://www.youtube.com) or Google Video (http://video.google.com) These sites allow you to upload videos. If you have a very nice machinima, you may want to make a website. You can do that through sites like Freewebs (http://www.freewebs.com), although you'd be better off with something more professional. If you are unable to make a site yourself, try seeking outside help.
