I have no idea why the link takes you to the wrong page - it works
fine for me.
In order to make comments on our web site you need to be a member of
this Google Group. Once you are a member here, you should then be
able to comment on the web site.
But it seems a bit hit and miss as several people seem to have
difficulty with this. The way it was solved for one member was to
delete his membership here and then rejoin here again.
