Snitz is fast and great. But it is not already for multi-language.
If snitz could make the words like Forums, Topics, Posts, Last Post, Home, Profile, Register, Active Topics, Members, Search, FAQ, Author, New Topic, Print Friendly, etc. manageable and changeable in the Admin Interface, it would be better. Like what has been dealed with the Forum Name("Snitz Forums 2000"), these data could be placed in the Table "FORUM_CONFIG_NEW".

there are multilingual version around, try searching for Images forum at google. thee is also a .net version which is multilingual
