from the RC2 feature list:
"All CB fields are Language friendly (may contain _UE_-type strings)."

I searched the forums for an answer, but it seems I'm the only one with this problem.

I tried to define a constant to be used in the welcome e-mail in German, English (& later in Chinese, BTW is there a Chinese CB community somewhere?).

I defined the constant _UE_WELCOME_MAIL in the germani.php & the default_language.php, & put it into the field in the configuration manager, but all that arrives in the user's inbox is _UE_WELCOME_MAIL (or [_UE_WELCOME_MAIL], since I tried that as well).

A similar constant defined for the registration introduction text - _UE_WELCOME_REG - works well.

What am I doing wrong? Or is it a bug? Or...?

BTW, Joomla 1.0.9 with CB 1 stable.

Did you find a solution for this problem, I'm having the same problem.
