Hello, we are using Windows Messenger 5.1 with plus 3.52.  I was wondering if there is a plug-in where I can create an icons where I can click and it will respone to another person?

I know I can bind Alt+1 to a messegne like "Yes".  Is there a way I can setup an icon where I just click on it and it would reply back as Yes without Alt+1?  Or how can I create my own menu item to reply back as "Yes"?

Thanks in advance.
