I want that JohnCMS add the two language in their official Releases.
¤Why you should add Bangla .

The world get The International Mother Language day for bangla. Bangladeshi people is the one and only in the world who have fight for their mother language. Bangla it 4t most used language in the world.
So please sir add bangla in JohnCMS...
