It wouldn't have made any sense to turn the features back on *before* putting in the new webserver. They were removed because the old server couldn't handle the load. They were put back in the instant the new server was installed. All features should be functional that were previously disabled.
I'm seeing a bottom menu.
Matt turned off the registration briefly because he was getting flooded with registrations from a terminated/suspended member. I thought this was over a week ago and he's turned it on since.
So which "present problems" are you referring to? I'm aware of very few bugs, but tons of feature requests. I'm working on the message-filing one and won't be doing anything else until it's done.
