this network. In addition to the alumni are the so-called SSE IFL Networkers, previous participants at IFL open or custom programs, these sum up to an additional 10 000. SSE maintains contacts with its alumni in a number of different ways; both through direct and indirect contacts and through various types of communication channels. Contacts are administered through the SSE Alumni Office. Today, many alumni are involved in the school's advisory board, the alumni association's board, the Student Association et al., all aligned to SSE activities. Even more alumni return to the School as guest lectures, or sponsors of course projects, as suppliers of internship opportunities, or as recruiters from large companies. Currently, if an alumnus wishes to connect with another SSE graduate, they have five primary options: 1. Attending the alumni events arranged by SSE Alumni Office 2. Networking through the SSE Alumninet, a web portal open to holders of an SSE diploma. Alumninet had some 14 000 members as of January 2013, or through the official LinkedIn groups maintained by SSE 3. Membership in the Alumni Association of the Stockholm School of Economics – an alumni association sponsored and organized by alumni for Swedish-speaking graduates of SSE – or by joining the American Friends of SSE – an affiliated alumni group, based in the US. 4. Joining any of the unofficial alumni groups and networks, maintained by the alumni themselves, e.g. in the UK.
