Shambles, I too am sorry to see you go. Yours were among those contributions which made me stay after I first came to find the answer to a question, and then stayed to see if there was anything I could do in return. One of those who made me feel at home on the Mudcat, who made me feel it was worth staying here when things were a little shaky. Let the light shine (even if it's only on the tail of an insect).Penny
