Erratum

A Feb. 20 article [“Ban Approved Despite Student Protests”] referred incorrectly to the Housing Office rule that was reviewed by a committee that recommended an unambiguous ban on flags and other materials on the exteriors of dormitories. The committee’s report reviewed MIT’s “Alterations and Additions” policy, which says, “Residents are not permitted to alter or add to any part of the building structure, mechanical, or electrical systems.” It did not review the “Fire Safety” policy.
