Improvements can either be posted here or sent in via feedback. And, if you post them here, we're going to tell you to send in feebcack anyway since that's what staff has told us to do.
1) Won't work. We've had a ton of threads about this already. Do a search for captcha and you'll see them. Machines can read most of the systems out there, some don't work for those behind broken proxies like Comcast and me when I'm over at CPCC, those with visual issues can't see them, those with issues with keyboards have issues with typing the correct response, it's a pain in the butt, etc. Staff has stated many times that this isn't going to happen.
2) Gotta agree with that one though, especially with my typing. :)
