Forums / Cotonti / General / Switching languages

I have a simple question:

Can I have flags to switch from language on the index ?
I want to make an international site where (unknown users) can switch from language.

Off course I understand that I have to have multiple articles eg. one in dutch, one in english....

And maybe this is an idea that we should develop in cotonti...
put an extra field on an article or on the structure for the language and filter it by using the url.. &lang=nl or something like that. (or put the language selection in a cookie...)

I think a lot of users want to have sites were they can switch from language.
I build commercial sites, and I am missing this in cotonti.

Looking forward to the response on this...
