Hi,

I am creating a bilangual website, which is both in a written language and a signed language.
Not any language module is supporting both textual and visual (flash) content.

No problem, I'm working on this.
But I'd need to know, how can I alter all the existing links in drupal so that all the links are carrying either "&lang=en" or "&lang=sign" at the end?
Which file do i have access to alter all of the existing links before they go to the website visitor (non-registered)?
I'm using drupal 4.7.x and will use $_GET to decide about the language output.

Thank you,
s7en.
