Welcome to the OSI on WWW page!


Due to a fairly recent disc crash combined with an incomplete backup, these pages have been restored to the way they were before Christmas. Much of the 'inter-page linking' and 'polishing' was done since then, and has been lost. :-P Normality should be restored within a few weeks or so, time permitting.
