Hi ya'll

I've been going through the paleolist site archives slowly, and maybe its
just the few sites I decided to skip that are giving me problems but...

1) What exactly does a sweet potato look like?  Is it the purple one on the
outside, yellowish or orange, cooked? Is this the same as a yam?

2) I can read many recipes, but what I really want is a very complete,
comprehensive, and to begin with liberally oriented list of paleo foods.  If
you know of one online, please let me know.

Thank you so much and
yoi yoi o-toshi o
