We love free. We scour dumpsters for free stuff. We take things that we'll never use because they're free. Free is rare and usually a little worn-out. Or it has so many strings attached that we end up hog-tied. But sometimes in our search for free, we get lucky and score big-time; we find the ElectroWave on Miami Beach, a 30-day trial membership at the gym, or the Southeast Florida Library Network (SEFLIN) Free-Net, which provides Internet access and e-mail accounts to South Florida residents, homeless people included, at no charge. SEFLIN also offers several free Internet training sessions each month. Registration forms and training schedules are available at most libraries, including the one on Florida International University's North Campus. Once registered you are eligible to enter the fast lane of free: the information superhighway. Of course donations are accepted.
