Like in topic. How to turn on recaptcha for registered users?

I'm thinking that in future CA releases will be good to include options for:
-Changing recaptcha theme;
-Turn off recaptcha for guests;
-Turn on recaptcha for registered users;
-restrict allowed time between questions/answers

Anyway, I'm happy about Community Answers and recommending it for everybody. I was trying before Simanswers on my website but the first thing is that it using almost the same look template as Yahoo Answers (any legal questions?), the second thing is that Community Answers have better code to understand for amators like me, and third, I can't Imagine how CA can crash my all website and Simanswer does twice. So I'm moved to CA and I see not only extension with big potential but great support as well :-) I think that Maverick don't sleep to much :)
