I sent in a check for my subscription to SGI-USA publications. Today, a week and a half later, my check is returned in the mail with a letter. Sometimes I write my checks in purple ink, just because I like it. SGI-USA will not accept my check because it was not in blue or black ink. What the ??? Who does that? I now notice that the letter has a line in bold type stating that the check needs to be written in blue or black ink. I thought SGI-USA was using a subscription service. Why do most things technical involved with SGI have to be just slightly off? From a business point of view, I thought this was funny.
