Arabic Spelling Check in Gmail

I was thrilled today while replying in Arabic to an email sent to me when my hand automatically pointed and clicked on the check spelling link in gmail to find that it was actually able to detect and check the spelling of my Arabic written email! That was really thrilling, for I had been really frustrated for long finding that the spelling checker in gmail supported English but not Arabic. Google is bringing more and more support for Arabic in its products. I hope the day comes when Google opens up AdSense for content for publishers of Arabic content as well.
