Wikipedia:Former administrators/reason/resigned

Resigned: These administrators voluntarily relinquished their adminship (some of these cases, though nominally by user request, are not entirely voluntary). Many of these users requested that their adminship be revoked either because they were no longer active at Wikipedia, because they were chiefly interested in editorial contributions rather than technical administration, or because they wished to focus on other Wikimedia projects. However, some administrators resigned in recognition of the community's dissatisfaction with their activities. Former administrators who resigned their adminship in good standing may be reinstated at the discretion of any bureaucrat after a 24-hour wait period to evaluate the circumstances in which they were desysopped. Administrators who resigned under controversial circumstances must reapply for adminship by the usual means. Unless otherwise specified by the Arbitration Committee, the determination of whether "controversial circumstances" existed is left to the discretion of the bureaucrats.
