I think, this is the best chat. It uses NO MySQL, but it has the Best Admin-Configureation, I know. There I can insert more than 300 Smilies, create new rooms and and and. It will be updated every time! The Board-Support is super. So, thats the Best chat I know. Maybe the static should be work without a Cronjob and the user should see just, that be said after his Log in. He shouldN´t see that, what be said before the user has log in!
