We've got a site which is in 10 or so languages, each of them being contained in a template group, en, es, de etc - so essentially the index page of each of these template groups is the homepage of that language and usually, clients from that region don't go to any other language.
However, when they first login they go to the default template group - English - which is the site main template group. From there they choose the language they require.
Is there any way to skip this and have the user redirected to their own language page on login?
Anyone done something like this?
