For all public communications, the language of opt-net is English. Opt-net is not restricted to the special interest group for optimisation. Anybody, anywhere in the world, with an interest in mathematical optimisation, and who has access to electronic mail, is encouraged to participate. In addition, ZIB also runs the electronic library eLib which provides the following services.
All information distributed by opt-net is public.
Even those who are not registered participants have access to its data by using ftp, electronic mail and various dialogue services. Registration is nevertheless a prerequisite for using its e-mail services, and for automatically receiving the weekly digest. The use of opt-net's services and the registration are both free of charge. If successful, opt-net will serve as a model for similar electronic forums serving other parts of the mathematical community. In the following, we briefly list some basic information on registration and use of opt-net and the white pages.
