What registration captcha options do you use at AdminAddict?

I ask because we are on 3.8.2 with the default and I want to beef things up with a better captcha and maths question like you have here.
There is no hack on vBulletin.org. Can you give some pointers where I can get the same changes to my registration process?
Thanks

 

Welcome Spinball!!!

Good to see you here. : )

 

Thanks for the welcome. Do you know me from somewhere

 

I've watched your sphinx search demo on the avs forums a few times (thanks!), used your forums for research, and also watched you post a few times on vb regarding the vb4 upgrade. I appreciated your input was on that topic.

But I'm just another random person on the internet with a small vb forum, especially small compared to yours.

Thought I would say hello.

 

Anyone?

 

Built-in reCaptcha with the NoSpam and StopForumSpam modifications from vBulletin.org. That's our setup here.
