We would like to inform you that as of 1 May 2001 we have moved to an on-line system of manuscript tracking, entitled ManuscriptCentral. You will be able to follow the whole review process of your article on-line, without going through the Editorial Office.
Glossy figures are no longer necessary.
Figures can be uploaded in .jpg, .gif, .tif, .pict or .bmp formats. If you have access to e-mail but not to internet, you can provide us with a diskette or an electronic version of your paper, and we will upload it for you. You will receive regular e-mails on the progress of your article directly from the system.
