Roger,
I just tried a search of "ASQ en espanol" and there are quite a few listings. Since I haven't had any spanish since elementary school, I have no idea what most of the choices are but maybe you can find something useful. Also, if you are a member of ASQ, perhaps your local section could give you some help (or even headquarters).
Perhaps you could even browse through the Cove Forums main listing and ask some of our "Spanish speaking" members if they could help you out.
Bill
