== A "thank you" letter == 
 Dear Sandy, thanks once more for helping an old man out with Rotavirus without my having to ask. It is very kind of you. I seem to be generating "white space issues" in my contributions, but I don't know what they are, (well, to be honest, I don't understand much Wikispeak but I can just about guess what  "FAC-nommed" means from my enlightening experience with Virus!)  Rotavirus looked better after you had applied your skills - how is it done? Best wishes from England. GrahamColm
