Our apologies to our website visitors on 12th July. We went off-line for a few hours late in the afternoon. We discovered that a spammer was exploiting a security hole in one of the modules on the website and using this to send out hundreds of false messages. We had to take the site offline while we fixed it.
We think it is now fixed but, as a precaution, we have disabled the page forwarding function. This is the one you access by clicking on the "Email page" link toward the top right hand corner of the window.
We will restore this capability once we are sure that the problem is properly fixed. In the meantime I hope neither the outtage or the removal of the 'forward' function has inconvenienced you too much
