TESTCASE

1. As an output checker create a new discussion post on a request

EXPECTED

The researcher would receive an email like this:
Hi <researcher name>,

Your request <request name> has been updated by <output checker name>. You may access your message via the "Discussion" tab on your request in OCWA.

ACTUAL

Hi <researcher name>,

Topic <request name> has been updated by <output checker name>.

Note: not sure if this simply a configuration thing or if it requires code changes.
