Most common languages are supported by SharePoint 3.0
Language packs are installed upon request by a customer. Once a language
has been installed for one customer on any particular server, it becomes
available for all customers on that server. A language must be selected upon
site creation and NOT afterwards. Once the main SharePoint site has been
created, different languages can only be selected when creating "subsites".
If a language other than English is required for the "main" SharePoint
site, that requirement MUST be specified when ordering the Alentus SharePoint
Hosting Plan. Once we have created the SharePoint site for you, the language for
this main site cannot be changed. Instead, the site must be torn down and
recreated from scratch with the new language selected. Any content that has been
added would be have to be deleted.
