> I also think it adds little value, and will likely offend a number of attendees, to enforce everyone to tick a "I will abide by the CoC" box. Do obviously reference the CoC, including using a 1 sentence version of it which gets read.  If people are going to break the CoC, they will do so whether they tick a box or not

Every single person who registered for FOSS4G 2014 had to click the box. No one complained.

Which isn’t to say that it’s some sort of panacea. At the very least it’s a “you can’t claim you weren’t informed” even if you aren’t paying attention.
