I had to turn off automatic registration for the site because we're getting attacked by spammers.
Our traffic is artificially high, and I've had problems with our hosting company because we have too much spam traffic. I don't think most people will be happy waiting for approval when they sign up. And that's also an imperfect solution as I can usually identify spam accounts but it's not guaranteed that I will always be correct... so I have to work on some other solution but it won't be until this weekend.
Just a note to let you all know the spam should slow down from now forward... but also new members, which is not good.
