Questions about SharePoint 2010 multi-language support

I have 2 questions about SharePoint 2010 multi-language support. My situation is this: I have installed a SharePoint site 开发者_如何学编程and create a web applications with two languages.

1. My customer wants that when he enters the website, Sharepoint should automatically recognize the language of the browser and set the site language. Is it possible to do this with some configurations (without writing code)?

2. I want to have my site content in two different languages and I know that this can be obtained with variations, but in my Site Collection Administration the Valitaion Menu (Validations, Validation labels, Variation log) don't show up. As seen in this blog post http://blogs.msdn.com/b/ecm/archive/2010/04/12/variations-in-sharepoint-2010-connecting-people-with-content.aspx, the Site Collection Administration has a lot of options menu, but in my site I have only a subset of these menus...

The answer to your first question is very simple: no. When a user selects a different language, that choice will be remembered for future visits. There is however no option to make the browser language determine the default language in SharePoint without coding.

Luckily I can also give you some good news. :-) Variations are part of the publishing infrastructure. You can make them available by activating the site collection scoped feature 'SharePoint Server Publishing Infrastructure'.
