NEW YORK ( TheStreet) -- What's happening in small business today? 1. Facebook's external email system. If you didn't know beforehand that Facebook ( FB) has an email system attached to its messaging features -- you do now. And since most people don't know about the email system, the social media giant has been -- unknowing to most users -- switching users' email accounts from their external addresses to a Facebook email address, according to Tecca. Tecca points out how to change the Facebook-chosen email address (which usually isn't very intuitive) back to a previous non-Facebook email address. For small businesses, giving customers a way to contact them, especially in the digital age, is of upmost importance but you shouldn't rely too heavily on Facebook or any other social media site as the only way to communicate with customers. More importantly, it's also a lesson in regularly checking information about the business on the social media sites to ensure there aren't any unexpected changes. 2. What's at stake in the Supreme Court ruling on health care reform. A CNNMoney report shares how the Supreme Court ruling on health care reform could affect one small-business owner and his family. Evan Rosenberg, a self-employed software developer already pays $1,800 a month for health insurance for his family of four, due to a previous motorcycle accident he had a decade ago. In August that premium is rising to more than $2,000. If the provision in the law that requires states to create insurance exchange disappears, Rosenberg could be forced to take a full-time job just for the insurance, CNN Money says. If he can't find one, then the onus will be on his wife to increase her hours at a nonprofit in order to provide the family's insurance, which would be a big setback. She recently decreased her full-time hours. For the Rosenberg's daughter, who is 24, she is already struggling at paying her rent and other bills as a full-time waitress (the law currently covers dependents until they are 26). She is hoping to open a yoga studio in the near future. 3. Kid franchises tapping into a profitable market. Franchises catering to the children's market and the parents that will pay for the services were plentiful at the International Franchise Expo earlier this month, according to Entrepreneur.com. A good example is Cool de Sac, a full-service restaurant catering to keeping kids entertained and fed with healthy meals while adults can enjoy "grownup fare." Another new concept is Kidokinetics, which offers sports programs in schools, camps and at birthday parties, or British Swim School, a U.K.-born concept that was recently brought to the U.S. The company teaches swimming to infants. -- Written by Laurie Kulikowski in New York.
