'they have yet to work' Is it a right expression? I searched about how to watch hulu. I found some articles. I looked one awkward expression below Guy1 i think u could use a proxy only and solve the problem. i sometimes use this one :[www.mariettalighting.info] Guy2 I've tried more than one proxy but they have yet to work. What does 'they have yet to work' mean? I guess it means that they doesn't work yet. Is it a kind of idom? or what?
