Should I said something? (Bogus PhD)

[MidLifeCrisis]

If you can let it go, then I think you should. I can't see how bringing it up works out particularly well for you, and it could end badly.

If you must bring it up, then the call above about doing it anonymously is a good one, I think there is merit in doing it via letter (typed and printed on a computer not at the institution and posted from somewhere generic, not your local) is a good one. EXCEPT you have to be prepared that nothing will happen. That could mean either what happens is unknown to you, or that the institution either is in on it, or doesn't care and literally nothing happens.

In either case, to not out yourself you have to be able to be ok with that. You have to be able to post the letter/send the email and leave it. If you are going to have to do that anyway then why bring it up to begin with...
