I just discovered that I have a ton of people on my unconfirmed list... and I've figured out how to see what forms/landing pages they've come in on... it appears that many are spammers. I have captcha on some of my pages/forms and not on others and now I can't seem to find the place to activate that feature. I think I can find the help info on that. In the meantime, anyone have suggestions for best practice for what to do with these unconfirmeds?
