MyBB Community Forums

I make a free WordPress blog . Now want to make MyBB forum for my blog with Bengali language. But I don't know how. Can anybody suggest me ?

I didn't use any web hosting. I made my wp blog form http://www.wordpress.com

Either get a web host, or go to a forum host like http://icyboards.com (although, I don't believe they support other languages.

Thanks for your information Stefan C.
