Due to a combination of more complications than I expected (there's a lot of moving parts when you're replacing the whole login system!) and RL interfering, it doesn't look like I'll be able to get this done and thoroughly tested before late today or tomorrow, and I don't want to send it live just before a weekend when I'll be away. (I expect there to be a number of bugs remaining that won't show up until everyone's using it, and I'll need to be around to fix those quickly.)
So, my apologies, but this is going to be delayed at least into next week.
