Okay, after much lucky guessing with regards to the user object handling, I have an ALPHA VERSION of a plugin to do this. There’s nothing to stop spambots, this is purely a proof of concept, I’ll try adding a captcha or something later if necessary. Email verification sounds like a royal pain though. Save the files exactly where I’ve said and as ever, make sure you leave no whitespace around the PHP tags. Apart from that, please test it but it’s your own risk if you run it on a production server.
