It has the "Redirect to:" option set. However, when I "wheel-clicked" the link "Send Email to xxxx" in order to open the link in a new tab, the forum broke out of its embedding showing this on the address bar:
That page isn't implemented in the NAML language, so embedding won't work perfectly (there is no easy fix). I don't think we have to worry about that because that page isn't used so often and if the user goes back to the forum the embedding will show up again.
