Yes my own forum. Also this one.
For example. Say you need the albanian language section on here. The sub forum is already on the main index page. Its really simple. You just click on the Albanian forum et voila. However if your language is not listed and you need to use the parent forum only, every-single-time you go onto the parent forum, you have to scroll down through 29 sub forums, just to get to the parent forum posts and topics you want.
The reason no other forum does this is obvious.
