Can I write in Arabic?

Yes and no.

You can write in عربي if you know the html code for Arabic letters, or write the message in Arabic in a Word document, save it as a webpage, find the encoded letters, copy them, and paste them into the forum message.

Admin, why is writin in arabic not so complicated as u stated? أكتب بدون أي مشكلة

Glad it's easy. Thanks for the info. Perhaps they changed the system since January.
