How do a upload a bump?
To upload a user bump, upload it to a video channel on YouTube or Vimeo or something and then share the link on the User Bump thread located here (http://www.bumpworthy.com/forum/index.php/topic,353.0.html).
To be specific, you can't upload videos to this particular site. Only the admins can do that.
Exactly. On-site bumps are only bumps broadcast by [adult swim]. User bumps are more than welcome in the forum thread, however! If you have a recording of an [adult swim] broadcast aired bump that we don't have, feel free to PM.
