Actually I'm using phpBB3 for my board.
But XenForo sounds pretty good and I'm thinking about a software exchange. But I prefer an support board in my native language: german. Is there any official german support-board like www.phpbb.de or www.vbulletin-germany.com?
In addition i'd like to use a german language pack, when i've paid 140$. But i won't use only 3rd partie packs created by fans, where i can't be sure that they keep them up to date all the license time for me XenForo Board.
