What a crock of sh.t!!!!! That's just your leader being lazy I reckon!!
It's real easy to convert recipes, I've done heaps of recipes - Converted them from ingredients to calories, then SW Syns, Old WW Points, and then new ProPoints... Sure it takes a few minutes, but to chuck the recipes out? Idiotic suggestion!!
I agree about not chucking them out. I've got a load of SW books, but I wouldn't throw them out, I'll just spend a little of my time converting them to PP.
