What did you want to know? I assume your over a certain age, so you won't qualify for any work/visit program which is targeted at younger Americans to work mostly in the Tourist Industry. Home prices keep climbing, many say there's a "bubble", read into that what you want. I know a fair amount about AU/NZ, I just don't have any first rate expat information like I do about Europe or even South America. I will say finding a mate shouldn't be TOOO hard.
Actually, those are kinda hard to run down and to be harshly frank, many of the members of these types of forums are WHITE WOMEN. So you get that funky perspective like "You should speak the local language" type shit. Which is reasonable but Women seem to think its romantic or something. The one web site I visit the most has some activity about Germany on it, but not specific location and its mostly populated with British Expats and you know where they go - USA, Spain, France.
