Participants are encouraged to bring their families. Workshop: A 40-hour workshop, intended for anyone with commercial software development experience who wants hands-on familiarity with the issues and technology of financial cryptography, is planned in conjunction with FC98, to be held during the week following the conference. For more information on the workshop, please see the URL http://www.cs.berkeley.edu/~iang/fc98/workshop.html. For workshop registration, see the URL http://fc98.ai/. Special Attraction: On Thursday, February 26, 1998, there will be a total eclipse of the sun. The narrow zone of 100% totality will pass just south of Anguilla. A boat excursion to the center of the eclipse zone is planned, for an optimal view of the eclipse. The excursion is included in the conference registration; additional tickets can be purchased for accompanying persons. Venue: The Inter-Island Hotel is a small 14-room guest house with a large, comfortable 150-seat conference facility and additional space for a small 10-booth exhibition. The Inter-Island is on Road Bay, near Sandy Ground Village, in the South Hill section of Anguilla. The conference, workshop, and exhibition will have TCP/IP internet access. Shuttle service to the conference will be available. Air Transportation and Hotels: Air travel to Anguilla is typically done through San Juan for US flights, or St. Maarten/Martin for flights from Europe and the US. There are also connections via Antigua. Anguillan import duties are not imposed on hardware or software which will leave the island again. There are no other taxes--or cryptography import/export restrictions--on Anguilla. Hotels range from spartan to luxurious, and more information about hotels on Anguilla can be obtained from your travel agent, or at the URL http://fc98.ai/. A block reservation has been made at Mariners, and this is the recommended hotel except for those seeking budget accomodations.
