Sula, you Brits and your use of "funny" words - I never heard of "valves" for "tubes" - I mean they look just like tubes and unlike what I think as valves.  LOL. 

Yes, Sula, you and I, along with our Agoracom family are lucky to be in Poet; it's looking so good right now. Looking forward, as always, to hearing Suresh tomorrow.  The man is truly a visionary.  Even though I was initially very impressed with him when first introduced to him and his style at his first AGM, I had no idea just how creative and brilliant the man is.
