I would be interested in taking a course in COBOL. I recognize that COBOL is considered a legacy language, but it is still very much in use (apparently) in business and banking. Unfortunately, it is not offered at my local universities or colleges, and I haven’t found a good (read easy to get started) online offering. I realize that this is very niche, but I also think there may be legitimate demand. I hope there may be others out there who are interested in learning this language.
