Believe it or not, my dad doesn't use computer. He doesn't know how, and he obivously doesn't care much either. Everything he use computer is only for checking his stock online and that is it!!! So email would be too fancy for him.
I am actually thinking that I can do it with only local phone service. One of my ex-roomate use to call his mom(in taiwan) via internet phone software......so..I am guessing it's also possible to fax over internationally, right?
