First Class offers low cost instructor lead classes on career, finance, arts and inspirational type topics. These are informative type courses which you would not find in your standard community college or learning center. They allow people who have a skill to teach that skill to interested people.
For example I took the The $100,000-a-Year Infopreneur class. It was taught by a knowledgeable person who started off with a "How to get a credit card processing account" years ago before even mail order became big. His class had good information with both how-tos and real life examples.
