Question and answer verification for new user registration is talked about in this thread, but I couldn't find a suggestion thread specifically asking for it (and I looked really hard - you know, as hard as you can look in a forum with 50 pages of suggestion threads). So here's a thread requesting it. reCAPTCHA is cute and all, but it doesn't keep the trash out nearly as effectively as question/answer does. If I'm late to the dance and there is already a thread specifically requesting this, then I suppose I've gone and ruined everything for everyone. That's why we can't have nice things around here.
