I'm in the same boat and it's been driving me crazy, particularly since the SC directly said that they'd be contacting us all with news one way or the other by a specific date which has already passed. It's completely taboo for me to contact the SCC and ask what's going on, right?
I'm used to hearing nothing from schools that didn't even give me a first-round interview, but hearing nothing after an MLA interview just feels cruel...
The chair of the search committee I'm on said similar things to our MLA interviewees. However, I know that we can't communicate with them until after a contract is signed due to HR requirements. We are in danger of losing the position if we break these protocols. We do keep the wiki for our job updated though. . .
