Camille, thanks for saying my name was 'splendid' but, in fact, this is my dad's email address- so it's not my name. as for the invisible ink problem, it's not your computer but this piece of junk. i don't know the technicalities of it, but it won't happen again as i'm unsubscribing today and resubscribing at my university address, where the computers are much better, so you'll be able to receive my gems of discussion without difficulty.
