With the recent bully tactics employed by Russia, I thought you might invite your readers to pen a message to Mr Putin. I just found a website enabling anyone to directly send a letter.
The site is the Russian Kremlin and it has a form allowing you to send him a message. This is the link: http://eng.news.kremlin.ru/
On the top menu there is a link “Send a letter”. It needs to be written in Russian script, but there are internet sites enabling you to do just that by copying & pasting, eg: http://translate.google.com.au
It must be addressed: To the President of Russia and not be more than 2000 characters. I just forwarded a piece and realized many more people might like to send something.
