Well, I've also been working on bring the online registration system up for Costume-Con 26.
Along the way I broke it.
The ENTIRE website.
We finally found the pesky misplaced double-for-single-quotes culprits (and an equally pesky change in the way PHP handles mixed form variables), but I was, as you might imagine, rather focussed on bringing it back online.

But it won't actually take you past the second step at this point. I still have to activate the recording and payment gateways, so IT DOESN'T ACTUALLY WORK yet.
But the rest of the website does.
