Kayakamina, I had already completed the Mephisto and had it in the postbox by lunchtime on Sunday, so when I saw this question I was in a good position simply to answer it. I had no idea that it had been asked earlier nor that YOU had already answered it elsewhere.
The reason I posted the link to my earlier answer, was to suggest to crucifernz that it is worthwhile making a search before posting a question, especially as she is in a different time zone.
Hi Kayakamina
I did do a search on 'Mephisto 2580' first, but it turns out the relevant question was posted as Mephisto2580 (without the space) - which is how I missed it!
Sorry, K...I don't know what came over me! For some reason, I saw your link as a sort of rebuke, almost a suggestion that I'd "copied" from it. The minute I submitted my response, I thought, "What a plonker!" Me, that is, not you, but it was too late. Let's just forget it, eh?
