Thanks for asking. I am using Google IME which is a great tool. Essentially, you type in what you want to say phonetically in Roman letters, and then it is translated to the equivalent Persian lettering. It's kind of like how Romaji works for typing Japanese in Roman letters.

Of course, I still have to mess around with it a lot to get the correct spelling or the correct word, but other than that it's great. Otherwise, I'd have to use a Persian keyboard for which my WPM (word per minute) is somewhere around 10 or 12, whereas with an English keyboard I have an extremely high WPM.

The Persian language uses the Perso-Arabic script (four more letters than Arabic), where letters represent sounds, and change form depending on where they are in the sentence. For example, the word نان meaning bread consists of three letters: ن ا & ن. As you can see, the ن letter occurs twice and takes a different form at the beginning of the sentence where it is connected to ا than at the end where it is by itself (don't forget that Persian is read right to left).

This makes learning the Persian alphabet a bit more difficult than learning the English language since you have to memorize quite a few shapes. However, it is still a walk in the park compared to learning a mixed-logographic language like Japanese. The upside of this kind of writing is that it makes poetry and calligraphy really interesting and beautiful.

It is also important to note that Persian is an Indo-European language like English. If you were to hear Persian spoken, you could definitely make out a lot of the most common words easily. For example, برادر is pronounced "baradar" which means "brother". In fact, it's probably one of the easier second-languages in the world to learn for an English speaker.

This is your post in Persian:
