As I pointed out on IRC, but just repeating it in here in case someone else actually wants to attempt it (Regarding the create via admin panel).
[00:22] <p858snake|l> mutante: don't use that function to create accounts [00:23] <p858snake|l> it doesn't send the emails to create it or lets you set the passwords, so you have useless accounts [00:24] <p858snake|l> unless bz has actually fixed that function in the last version or two since i looked about it
