I'll take a look.

I don't *really* have a bunch fully untrusted / bad users, in fact I
expect I will sort of trust all the people doing this level of coding --
but I believe that either incompetance and maliciousness is inevitable
in any sort of online community, and making it at least as hard as
possible to do damage while giving people as much freedom and tools to
do great is the ideal goal. :)
