How can I set the language fix or ext. for agbook 2.3.1 ??

Hello,

I want to give my visitors 2 languages for the agbook 2.3.1.

At the moment, I can only set the language in the admin section and it will be written in the database.

So I have a homepage, that is designed in 2 languages.

If someone comes from the german site, he schould see the guestbook in german automaticaly and if he comes from the english site, he should see the guestbook in english automaticaly.

How can I do this ??

Can I overwrite the lang variable from DB with an own value and fix it in the code ??
So then I will copy the GB in an extra folder and then the only difference is in this value.

Or is there an easier way for it (maybe a refferer from where he comes) ??

Regards

From a quick scan of the scripts you can make a variable in the cookie called lang in which you can specify english or german and the guestbook should honour it.
