If you are a man who has used the Internet to meet other men for sexual encounters, and are at least 18 or older, we would be interested in hearing about your experiences. Researchers affiliated with Columbia University are conducting a brief online survey that only takes 5 - 10 minutes to complete. Your participation is voluntary. You may stop any time or skip any questions you choose not to answer. You could win a $100 prize! Complete confidentiality assured. If you would like to participate, send an email to firstname.lastname@example.org for the link to the study.
