How can i translate an article on Wikipedia in a new language?

Easy, erm, Ashkan. The way to translate an article on Wikipedia into a new language is as follows. (1) You read a bit of the article you want translated. (2) You translate what you've read into the new language in your head. (3) You write the translation into the new, Farsi article you've just created. (4) You keep on truckin' like this until all the original text has been translated, and written. (5) You step back, look at your brand new Farsi article and say to yourself "Gosh. That was easy. And to think I wrote in to Yahoo Answers. OMG!".
