The article discusses how genres shape identity and authority. It focuses on a case study of Alan, an IT employee in a university's humanities department. Alan struggled to adopt the expected identity and gain authority within the discourse community. The faculty saw Alan as a "tool" to manage computers rather than a full member, which limited his ability to enculturate and align within the community. Authority is socially constructed based on factors like language use, participation in genres, and perceptions of one's role.
