Request: Updating URL in the Training Box's Welcome email

Hi,

A little request:

In training Box, the welcome email has the following message with a URL that does not direct users to the training Box:
The URL is
https://app.clarizen.com/clarizen/default.aspx
when it should be something like:
https://app.clarizentb.com/Clarizen/Pages/Service/Login.aspx?

Actual Message:
Dear xxx,
Thank you for registering with Clarizen. To login, go to https://app.clarizen.com/clarizen/default.aspx.

Is there a way that the URL get updated for the Training Box as to avoid having users logging in the wrong environment?

Thank you
