Akhi Yassir Elsharif, This application needs to be installed on a web page. You can then use it from there to write your Arabic text. I think this is useful if you don't own the computer and you can't install any software like maktab on it. I'll provide the steps to intall it on the phpbb forum and other web pages.
You can test it on
http://sudadev.net/forum if you try to post anything there. The job opportunities forum there is open to guests to write without registering so you can use that to test. I don't have any live demo other than this for now
thanks to you
