The Zap power allows you to kick a user and make their chat shake while playing a sound. To use Zap, click a user's name then the "Kick" option. Type a reason and click "Zap".
To change the sound of the Zap (default is #raspberry), add a # followed by the audie you want. You can find a comprehensive list of audies here.
This power can be used in conjunction with Superkick to kick ranks that you normally would not be able to kick, depending on your rank.
