The Continuing Education department of Columbia Journalism School hosts its third annual Social Media Weekend, a series of workshops, panels and keynotes to help journalists, media professionals and others understand social media better.

In addition to panels and workshops, there will be a continuous group of Social Media Doctors offering social-media makeovers, tips and feedback in one-on-one and small-group sessions.

Attendees can receive nuanced assessments of their social media presence or just have someone explain the basics.

Professional photographers will also be on hand to take headshots for use as profile photos.
