Custom "presence" messages in Microsoft Communicator

Being annoyed by a wave of colleagues who are setting in permanence their status to "Busy" (just like everyone else was only surfing the web while at work...) I have decided to setup some funny custom statuses, like "fooling around" and "playing with my dog" and "VERY VERY VERY VERY BUSY :o)"

I have found several articles teaching how to do this manually, hacking the registry, but it never worked.... actually Communicator stopped working and I had to undo all the changes.

Finally I have stumbled upon this application and it worked at the first attempt. Thanks a lot! On 2007 R2 version.
