Dear Colleagues, for those of you that are not going through the effort to read the long e-mail I just sent out, here the short request: Please let me know as soon as possible (at least those of you that are not away from the office these days) what presentation(s) you would like to make at the planned IERS CPP Workshop in San Francisco. Send the information either to cpp@iers.org (to inform all) or to both, rothacher@bv.tum.de and richter@iers.org. A short e-mail with the topic of the presentation(s) is enough for now. We need your feedback fast to plan the amount of time to be reserved for the workshop. So, if possible, answer before Monday, 18 October 2004. Despite some negative comments, I still think that there is interesting and important new material to be discussed. From experience I doubt that e-mail exchange can replace a meeting, although it can complement it ... With best regards, Markus
