The trial will compare YT (N=175) to a control group (N=175). YLWH in the control arm will receive weekly static information-only emails, compared to daily use of the dynamic YT social network site for the intervention group. Participants will be recruited from six cities: Houston, Chicago, Atlanta, Tampa, Philadelphia, and the Bronx. Assessments will be collected at baseline, 5, 8, and 11-month follow-up.
