Well, it is complicated to say whether other language forums are needed.

Since I understand only two languages - Bulgarian and English, forums with different languages than these above wouldn't be understandable to me.

If there is a valuable to me content in these other forums I will miss it. This option sounds like a separation and I am definitely against it.

If the content is just translated and people discuss it in their most convenient language it is OK. This will bring additional people to the table and make it more accessible.

Still the way things are now is ok. I am pretty sure I won't see a Bulgarian sub-forum. The problems is that you have to read my crappy English.
