This is nothing really alarming, but just as a precaution I am asking everyone who made their accounts before 2013 (I think september-october but just to be safe, before 2013) to change their passwords. No, there is no present threat of any kind, but I made a stupid decision in the past that could potentially cause problems.
I won't discuss it at all and don't ask, just know that I am doing this as a precaution.
