We invite you to sign the Detailed Baseline Design (DBD) report of the ILC detectors, which now exists as a nearly final draft. It summarises the R&D achievements of the ILC Letter-of-Intent period. The contents reflect the many contributions of very many collaborators.
While this draft is undergoing minor revision following the recent review by the International Detector Advisory Group (IDAG) and the ILC Project Advisory Committee, it is almost in the final form.
A list of signatories will be included in the report. We wish to include those who contributed already in any way or who wish to join the activity in the next stage. We also would like to include names of anyone who supports advancing further the world ILC effort.
