Well, on my little laptop ( ) I've installed Firefox with some useful plugins, one of them checks emails on a webmail service (an address that I use to register on sites) and I was puzzled by the various webmail services that you could monitor. One of them was this "Naver" mail service, never heard about it ... So I googled it and found that it is a Korean site.
It took a long while but I succeeded in having a working email address there
So the challenge is: try to do the same, address is http://www.naver.com
Obvioulsy it's all in Korean, and yes, it will ask you for a Korean ID that is something like the unique social security number of the USA... But there is an opion for foreign people (find it), in this case, they will send you a control code on your cell phone (find the option...) then there is only a copule of checkpoints and you-re done...
This is one of the stupid things on which I use to spend my time ...
