Dear devotees, as you all know, the website had been kept open since the upgrade to the modern website that corresponds to 

It had been constructed with the Joomla interface and since there hasn't been any upgrade, there is a security risk that we must curtail.  Therefore, as of Sunday June 3, the old website will not be accessible any more.  We are sorry for those who liked the old way of searching the lectures with  the tables but this shutdown has become a necessity.

Thank you for your kind understanding.
