disallow signing in forum before approved

[fatherofspeed]

I want to keep new forum registrations from being able to sign in before their registration is approved (moderated). How do I do that? I hope it will keep the spam bots from using up my band width. Although I have it set to new users being moderated, they are still logging in and i assume that's where my band with is being sucked up.

any ideas?

Thanks.
