A bit of background on chat snippets... They have two basic parts: a DIV element which is the "chat loading..." part, and a script. The DIV is a placeholder that determines where chat appears on your web page. The script does the heavy lifting of contacting our servers and, if successful, replacing the "chat loading..." with your actual chat service which may or may not be online.
