  HpS - Jaya!   AGTSP   paoho.  We will see you very soon!    I hope we can talk on Skype soon.   We are realizing that we can only do so much work each day.  For example, today we spent time on Youtube with the Biography of Joan of Arc. Is very useful for preaching and calmed us quite a bit.   Many clases here in Radha desa.  We investigate your link!  Thank you.
