It's a board, where you can connect with people from Miami, find other people in Miami who share your interests and discuss them. I enjoy bicycling, so there's a bicycling forum for Miami Riders, as well.
You can also look for a job, buy, sell and trade on the Marketplace, get help with homework if you're in school, or discuss anything from Politics to Philosophy on the board. Please take a look. It's absolutely free, and will remain so.
