Sergio, welcome to the Mudcat. I am sorry you had to learn of such sad news. Thanks for posting about your friend.We have one member, Escamillo, who is also from Argentina, but he hasn't been posting much, lately.
I hope you will come again and join us at the Mudcat.
All the best,
kat
P.S. Kim, I cannot remember where I found that and I'm sorry I didn't respond earlier.:-) It was probably on google.
