/**
 *
 * Poke, prod, finger, or otherwise do unspeakable things to somebody - who must be a connection in your address book
 * This function can be invoked with the required arguments (verb and cid and private and possibly parent) silently via ajax or
 * other web request. You must be logged in and connected to a channel. 
 * If the required arguments aren't present, we'll display a simple form to choose a recipient and a verb.
 * parent is a special argument which let's you attach this activity as a comment to an existing conversation, which
 * may have started with somebody else poking (etc.) somebody, but this isn't necessary. This can be used in the adult
 * plugin version to have entire conversations where Alice poked Bob, Bob fingered Alice, Alice hugged Bob, etc.  
 *
 * private creates a private conversation with the recipient. Otherwise your channel's default post privacy is used.
