"The group’s concept is simple. People sign up online and get access to a database that is kind of like a members-only Craigslist. One unit of TEM is equal in value to one euro, and it can be used to exchange good and services. Members start their accounts with zero, and they accrue credit by offering goods and services. They can borrow up to 300 TEMs, but they are expected to repay the loan within a fixed period of time."
