We are asking everyone who wants to be listed as a supporter to go to the sign-up web page.
The list, to be made available on the International LC web page, will serve as a demonstration of the widespread support in the community for the linear collider.
See also the updated letter distributed by Jim Brau, Sachio Komamiya and David Miller.

International

• to contribute to the development of a Global Linear Collider programme by encouraging international collaboration on the physics case, on detector R&D and on the machine-detector interface.
• to participate in the international LCWS workshops (the Saariselka series).
• to explore ways of co-ordinating and perhaps integrating the regional and worldwide workshop series.

Detector design, R&D, Simulation

• to design, build and test detector prototypes (with inter-regional collaboration).
• to maintain the detector design, and critically review its performance on all important physics channels.
• to build up a modern simulation framework (both for detector and physics studies) sharing resources with the other regions whenever possible
• to prepare all tools necessary for a "simulated data challenge"

Machine-Detector Interface

• study the impact of realistic beams and the associated backgrounds on the detector.
• when the linac technology and crossing angle choice has been made, update all designs to match.
• interact with the designers of the beam delivery system to ensure that physics goals can be achieved.
• participate in planning and R&D for polarimetry, beam energy measurement, beam monitoring, luminosity measurement.
• study the special requirements of the gamma-gamma, e-gamma and GigaZ options.

Physics Case

• co-operate with LHC colleagues to develop and present the arguments for concurrent running of LC and LHC.
• explore the connections between the LC physics programme and cosmology.
• continue to upgrade feasibility studies on important physics channels, with more realistic beam, background and detector simulation.
• before the linac technology choice is made (end 2004), explore any differences between the physics capabilities of the candidate technologies.
• study quantitatively the potential systematic limitations on measurements and look for ways around them.
• quantify the physics benefits from options to upgrade or vary the LC programme: from the energy upgrade, from e- e-, e- gamma and gamma gamma, from the Giga Z, from e+ polarisation, from narrower beam energy spread, from better polarimetry and spectrometry.
• in the Loopverein: continue to improve precision of Standard Model and Supersymmetric predictions to match the expected precision of experimental measurements with the LC.
• to continue to investigate new theoretical ideas, both strategic and methodological.
• to continue development of Monte Carlo generators suitable for LC physics.
