M/s and in the UK? This page replaces the Masterslave.org.uk website which preceded TSR, and has some pointers for M/s people in the UK. Internationally, the largest-membership Master/slave and 24/7 D/s site is The Slave Register (TSR), which is based in the UK but worldwide in scope. Its M/s & D/s web board sometimes includes announcements about events in the UK, and the other boards include discussion on general M/s topics. TSR's personal ads listings can be searched for people in the UK. Master-slave-uk is a Yahoo Group run by The Slave Register for M/s announcements specific to the UK. The UK D/s & M/s web board on Informed Consent frequently has discussions about M/s and 24/7 D/s topics by people in the UK too. IC also has a member-run group dedicated to Ownership & Possession topics.
