I just got the chat package running. It's awesome. I was just wondering if the html version does an auto-refresh at all. I logged in twice and sent messages form one user to the other but couldn't see the messages on the other side.
www.cgecon.mre.gov.br (run by Rodrigo, Felipe, myself and others) has an auto-refresh version of acs 3.3 html chat, but it's too heavy on our database. We'll stick to the java-based version by now for our e-learning tool.
