Changed the API: The behavior of addToChat(message) is now at addRawToChat(message). addToChat(message) adds a timestamp and filters the message for HTML code. So using addToChat(message) does the same as addRawToChat((System.currentTimeMillis()) + "|" + filterHTML(message)). New API version: 3.0
Changed the chat system to use a timestamp in milliseconds instead of seconds. Update your .v10 files for that (in the simplest case just delete the file chat/out.v10 in your www dir. Then, at the next startup, a updated one will be placed there.
