As many of あなた know that 投票 from outside America don't count in Teen Choice Awards.Well I was visiting this Miley Cyrus ファン page -> link and I saw that there might actually be away to make them be shown as USA votes.

This might be new to some of you, but we can vote for the Teen Choice Awards via proxy. This is a very easy process so don’t give up.

Basically what あなた have to do is visit link This site is using a United States proxy which means your 投票 will be shown as United States votes.

あなた basically write TeenChoiceAwards.com in the box.

(click on the thumbnail to visit the site)

And then click Go.

That’s basically it. From now on you’ll be surfing the site as if you’re not using proxy.

Make sure あなた do it and spread the word!
