Hi Guys!!
I would like to know that is it necessary to include RTL (right to left) CSS file for WordPress theme submission on ThemeForest. This question is bothering me since I am unable to find the answer for it in the Submission requirements listed by Team Envato.
Not mandatory but always good to include for your potential buyers
definitely include, use http://wordpress.org/plugins/rtl-tester/ to test your theme
Thank you for the response guys! So, what I am able to understand is that its not mandatory but a good practice to provide RTL support to the theme.
RTL is optional but if you want to attract more people to purchase your items I recomment to implement it.
Regards 
Point noted Sir. Thank you for taking time out to answer my query
