This apparently not a burning issue. No one seems to care enough to make 
a simple change in a message. It is not that difficult. The developer 
workshops have offered assistance in in modifying code. There are 
probably how-to on the project web site.

Why have we gone to all the bother to create an open source project, if 
no one takes the time to make even the most trivial of changes to the code.
