What worries me about Trollheart is that it is so out of character for him to stop posting so completely, and without a word of warning. On a regular basis, he used to encourage us to treat each other as real-life friends here, didn't he? I would've expected minimum a polite note explaining why he was quitting, but AFAIK he didn't send as much as a one-line pm to announce his departure - so it remains a puzzle.
Perhaps his sister suddenly got really bad and he hasn't had the heart to continue here. Personally, I prefer not to go the route of TH having some horrible health crisis - though if Roxy rings him again in the middle of the night, she might induce a heart attack!!
A good time to make a transAtlantic call is between breakfast and lunchtime in the USA, Roxy.
