I guess this hasn't gone any further? I'm running version 3.6.1 and this hack isn't working
Something like this would be very useful to me also. If someone has come across to any ways to do something like this, please let us know
Also, I have encountered a strange behaviour, which I don't fully understand, it sort of relates to this. I have a forum with four languages, and four main areas, where the discussion is made in the language in question (so there's English discussion, where the language of the interface should be English, Swedish discussion, where the language of the interface should be Swedish etc...).
If I use URL with the GET-parameter for the language selection from an external source, it works just fine, the correct forum opens up and the language is right (such as
http://mydomain/forumdisplay.php?f=16&langid=2 to point to the English discussion and making the language selection to English). But if I set this URL to the category's Forum Link value, I get an error about redirecting (FireFox says: The page isn't redirecting properly, Firefox has detected that the server is redirecting the request for this address in a way that will never complete), and actually the links from the external source also stop working, why is this?
Anyhow, the default selection for forum's language would be much better choice anyway.
