I'm only able to post this by switching my document mode to IE 10 via the dev tools.
While I bet we are a minority, some of us do use the latest IE (maybe because we work at Microsoft, who's to say

). I'm not sure if this is a known issue with the Xenforo stuff or if they use another editor but it is just a blank box with errors spit to the console window in IE 11. I know these things can be finicky but I wanted to make sure this was on the radar.
