I worked on this as an exercise in 1. generating a captcha (not relying on pre-created images that can be spoofed over time) 2. having a countdown refresh timer of 30 seconds completely in CSS 3. No javascript so no ability to track user activity 4. A place for people to publicly and privately chat.<p>Private chats aren't working yet, but almost.<p>I haven't touched the project in about six months, but need to get some ideas and feedback to get back into it again.<p>Thanks
