In this paper the online construction of disability is investigated and the implications for educators working in virtual worlds are considered. Based on the analysis of data collected through interviews with deaf residents of "Second Life", it is argued that research into online identity, disability and education needs to allow room for self-description, and that educators need to recognise the power relations that can lurk within practices of provision or accessibility support. Working through these issues involves reconciling disability studies with e-learning and accessibility perspectives. It is proposed that strategies that would support this reconciliation might be found in recent literature on disability and technology.
