학교 공지, 도대체 어디서 다 확인해야 할까요? 학교 홈페이지, 단과대별 홈페이지, 국제처, 학과 사무실 공지사항까지 — 연세인이 챙겨야 할 공지는 사방에 흩어져 있습니다. 하나씩 찾아다니다 보면 정작 중요한 장학금 신청이나 수강신청 일정을 놓치기 쉽고, 필요 없는 공지까지 다 훑어보느라 시간만 쓰게 되죠. 연공은 이 문제를 딱 하나로 해결합니다. 내가 보고 싶은 것만 골라서 구독하는 것. - 내 학과/단과대만 구독하기 전체 공지 말고, 내가 속한 학과나 단과대 공지만 필터링해서 볼 수 있어요. 관심 있는 다른 학과가 있다면 추가 구독도 가능합니다. - 관심 키워드로 구독하기 장학금, 학부생 인턴, 근로장학생처럼 내가 필요할 때만 찾아보던 정보들, 이제 키워드로 구독해두면 놓치지 않고 알림 받아볼 수 있어요. - 학사일정 한눈에 보기 수강신청, 정정기간, 휴학 접수, 등록일정까지 — 캘린더에서 한 번에 확인하세요. - 북마크로 나중에 다시보기 중요한 공지는 북마크해두고 필요할 때 바로 찾아볼 수 있어요. 예전 서비스에서, 완전히 새로워져서 돌아왔습니다. 이제 흩어진 학교 공지, 연공 하나로 모아보세요.
