I'm pleased to say that after many months of being in the doldrums this web site is in the final stages of being transferred and fixed (again!). We were having no end of technical troubles but they are sorted now. Those who had subscribed to the site by email will soon receive requests to confirm their subscription to this updated site. Then we will be back in business.
There are lots of fabulous new resources that have been added in the meantime. I'll post a summary soon.
