Banned user creating havoc

You probably want to use the troll mod. I can't find it right now as phpbb is down but basically if gives the user a cookie which creates all sorts of errors for the user on the website. once you make the user a troll and he or she logs on it will effect the entire browser for that forum.

IIRC the Troll mod for BB3 is either in Alpha or Beta stage of development, so not recommended for live boards

I'm managing this by sending them back an e-mail requiring them to answer a couple of easy / simple questions and activating the replies. So far so good, with the above technique I'm catching all spam attempts and avoiding having hundreds of useless accounts.

OK, Ive now set my settings so that new members have to go thru the admin to get approved. I'd like to send them back as e-mail, but I'm not sure how to do this. Sorry that I'm a newbie but can you explain in detail?

Thanks for all the help!
