Yea.....turns out I thought that setting was "Do you wish for other members to see when you are reading a topic"? I thought it was something to keep your activities private. But now that I think about it, is that even an option for regular users?
Either way, I changed the setting and signatures are back...thank you.
Sorry for the derp.
EDIT: I had thought it said that late at night...and whilst on my android phone, if anyone asks.
