Visitors to www.forecasters.org/ijf will notice a big change to the Interational Journal of Forecasting website. Now all published papers back to Volume 1 can be accessed from this site. There are two new facilities that will change the way readers interact with the journal: comments and supplements.

Comments: It is now possible for readers to contribute comments on each paper via the website. These comments are publicly visible. The authors may provide responses if they choose to do so. So if you have any thoughts on published papers, you can now make them public for the benefit of all forecasters. You can think of this as an extension of refereeing, but post-publication and publicly visible. All comments will be moderated.

Supplements: Supplementary information about a paper can be provided by authors and will be available online. This includes data, computer code, large tables, extra figures, extended footnotes, extra relevant material, errata, etc.  Authors of IJF papers are requested to contribute a complete set of data in electronic form to the website, or provide instructions for how to obtain them. Authors will also be encouraged to provide whatever other material is needed to ensure that their results can be replicated without excessive difficulty. If authors of published papers have additional information they would like to contribute, please send it to Rob Hyndman at This email address is being protected from spambots.

The new website also provides links for article submission, guidelines for authors, and provides a list of the top-cited articles in the journal.

The schedule of speakers at the International Symposium on Forecasting in Hong Kong includes leading figures in forecasting Professors Scott Armstrong, Robert Fildes, Rob Hyndman, James Taylor, Lindsay Turner, and Stephen Witt.

Scott Armstrong was interviewed on the BBC "Five Live" show about forecasting the population of polar bears and climate while he was attending the International Conference on Climate Change in New York in March. The issue remains topical as lawmakers debate CO2 emissions laws.
