Hello all!

I was just wondering, I need to build a signup form with US states and  
also  
world countries selector. Is there already a helper os something that  
implements or makes it easier to implement this for Rails (Rails is  
making  
me lazy!).

Btw, where could I get a list of world countries and US states? Is there  
any  
webservice for that ? Or just copy and paste from somewhere else?

Thanks in advance,

Marcelo.

Google for the ISO standard 3166 - that’s the official list of country  
codes.  
ISO639 is the list of language codes, both 2-character and 3-character  
versions,  
depending on the revision of the standard. Both are covered in the  
IETF’s  
adaptations in RFC 3066, but check the ISO standards first.
