Michael, I'd just kept on with the original ITL layout, both for individual monsters, and also for organizing in the four or five groups. I'm not fussed either way - in some ways having more entries is good for fleshing out things one hadn't thought about (e.g. no. appearing etc.) It reminds me when i first got the monster manual with the entries a zillion lines long, and thought wow... (frequency/no. appearing/AC etc..).
I guess after spells, monsters are the next least controversial thing to put on line (at least until we discuss talents a bit further but I'll wait until a few others drop their 2c worth of opinions on us both.
