Send out a message to the group, such as the following: “I’m planning to be in NYC from DATE1 to DATE2? attending the “Workshop” organized by STEMteachersNYC. I’m “male/female” and am seeking a roommate to keep lodging costs low. Please let me know via email at ’email address’ if you are interested.”
The admin of our Facebook Group will be monitoring messages and will make sure that messages seeking roommates are on top. STEMteachersNYC’s Facebook Group now has a few hundred teacher-members, almost all of whom have attended our workshops, so you can assume that the recipients of your message will have a sense of the context for your request.
