[wg-all] Mailing List Changes
by Andre Merzky 03 Sep '06

03 Sep '06

Sorry for duplicates ------------------------------------------------------------ As of yesterday, all GGF/OGF mailing lists are migrated to the ogf domain. They are now managed by mailman, the web interface is available at http://www.ogf.org/mailman/listinfo With that migration, all list can be now reached via <list>@ogf.org The old @ggf.org addresses will be available for some time, but are bound to disappear eventually - please start using the ogf addresses! A number of lists have changed their names: ggf-it --> ogf-it ggf-office --> ogf-office ggf-proc-wg --> ogf-proc-wg ggf-sponsors --> ogf-sponsors ggf-tutorials --> ogf-tutorials ggf-compute --> ogf-compute ggflistowners --> ogflistowners ggfstudentmembers --> ogfstudentmembers Postings to the old list names get forwarded to the new ones. With the migration we have also been able to fix the archives - you may have noticed that list archiving stopped sometime in mid June. Well, now its working again, and all mails from June to now have been added to the archive. The list archives can be found at: http://www.ogf.org/archives/<list> If you are an list administrator, and would like to receive the list admin password, please contact postmaster(a)ogf.org. In general, however, we tried to map the old majordomo settings to the mailman settings, in terms of privacy etc, so no or little changes should be required from your side. The spam avoidance policy has been changed to some extent, and is somewhat stricter than before. Please let us know if you experience any trouble with that. On all questions in respect to mailing lists, or mails in general, please contact postmaster(a)ogf.org. Best regards, Andre. -- "So much time, so little to do..." -- Garfield -- wg-all mailing list wg-all(a)ogf.org http://www.ogf.org/mailman/listinfo/wg-all
