DontStayIn, commonly abbreviated to DSI, is a social networking site based around clubbing. Primarily covering the UK it lists nearly 185,000 events and has over 430,000 verified members. Members are encouraged to upload picture galleries to the site for events they've attended, add events and venues and otherwise contribute. 'Spotters' are DSI members who review and photograph events and promote DSI. DSI users (often shortened on the site to "DSIers"), have used DontStayIn to set up events and user-groups to promote the meeting up of DSIers in real life.
