If you're new to the ISSS, you can read about is origins and purposes on the About the ISSS page.
ISSS World is now the main content platform for the society. There are now only two userid/passwords for the society: one for ISSS World (that also works on ProjectsISSS), and one for JournalsISSS (abstract submissions for the annual meeting).
The old web site is available temporarily at http://isss.org/index-old.html.
