Send a second follow-up to inquire about interview success? I interviewed for a lecturer position a month and a half ago, and was told that the decision would be made about one month after my interview.  I was also told that I would be informed either way, but have yet to hear back.  A week ago I sent a follow up email, asking if a decision had been made, but didn't receive a response.  Is it appropriate to send another follow up, or should I just sit tight?  I have a feeling I didn't get the position, but I'd like to know for sure so that I can start planning other options.
You won't accomplish anything by sending another email. The department hasn't forgotten that they interviewed you.
