Well, I did have the letter here from FourGen Software, Inc., but after reading some discussion on a newsgroup, I think that putting their letter on the Web may violate copyright laws. I'm checking on that...
In the meantime, I'll just say that it was a very polite request for me to change the name of my files containing the FourGen (tm) name, so that people searching for FourGen Software on the net wouldn't find the picture of my family.
While the letter was very polite and reasonable, the situation struck me as being assanine...Hence my response.
