UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? How do I add recaptcha to UBB threads 6.2?

Hi - I love my boards and don't want the hassle of an upgrade, but I'm getting slammed by spammers and need to add recaptcha. I already have a key but don't know what PHP forms to add the code to, or where on the forms to add it. Is this info available anywhere?

Thanks,
H

Might want to try over at ubbdev.
I think there are a couple of captcha mods for threads 6.x.
