Dear Colleagues -- At the request of several potential speakers at the TUG'98 conference in Torun, Poland, the deadlines for submission of proposals and papers have been revised. The new deadlines are: Receipt of proposals: 15th March 1998; Notification of acceptance/rejection: 6th April 1998; Receipt of first drafts: 30th April 1998; Receipt of final versions: 30th May 1998. It would be much appreciated if those who have already submitted proposals would keep to the original deadlines; this will much help the work of both the Programme and Publication Committees by distributing the load in time. Full details of the conference and the procedures for submitting proposals may be found at http://www.tug.org/tug-98/ Philip Taylor, Chairman, TUG'98 Programme Committee.
