I just received a request to tell everyone how you can help the protesters in Iran.

Security forces there are hunting down people using Twitter with a location of Tehran and a time zone of GMT +3.30. You can make it harder for them and show solidarity by making your location and time zone on Twitter be the same. The idea is that if tens of millions of people do it, then the real people in Iran will be harder to find.

You can change your Twitter settings on your PC or even on your iPhone.

If you agree, please forward this posting to everyone you know.I
