April is National Community Service Month, as an email from the Office of Off-Campus Student Services cheerfully proclaims. And to celebrate, the office has organized a day — or at least two hours — of service. Emerson students are invited to volunteer at More Than Words, a local nonprofit dedicated to, as the email says, helping disadvantaged youth “take charge of their lives by taking charge of a business.” Participants in More Than Words are in foster care, involved in court system, homeless, out of school, or have learning disabilities or mental illnesses, according to its website. Emerson students will be volunteering at the organization’s South End warehouse and used bookstore. Those interested in the stint on Friday must RSVP by 5 p.m. today.
