We are having a problem with chat where the End Users are closing the popup chat box before we can get a chance to type anything.  Why in the world we are having a tough time getting users to NOT do this is frustrating, but the common theme is that they see this blank box (they are ignoring the name in the window header).

Is there a way to add a custom statement as a default push, by default, so that the client's chat box shows it once it pops up giving them a bit more information?  Probably a feature request, but was hoping there may be a method via a custom hack in the meantime... so by default it pushes <dc userid> is Online.
