Buddy Press Translations

Hi,

Just started using BP, and I need to translate it to Hebrew.
Usually I use WPML, but this time the whole site is hebrew, so I'm hoping to avoid using it.

Also, if there are good WPMUDEV resources to get up to speed with BP, I'd be happy for links.

And while we're at it - are BP user just like regular WP users on the site? can i let them write posts ect.? if so how?

Thanks,
Tomer
