Did you realize that your demo page for Collabtive does not allow the user to choose their language? It appears to default to Chinese for the user interface.

It's reset to English every hour. I've now reset it manually.

But you're right, the user should be able to select the language on the online demo before login. I will add this to my TODOs. Thx!

One of the burdens that comes with more than 40 locales... ;-)
