You have to code it yourself ... It's not something that can be done very fast and without big effort ... If your PHP knowledge is fair, I can help you make shoutbox.php that you can include in lgsl_details.php ... And it will have different messages for every server ... I made it for my site too, check here: http://gametracker.rs/index.php?page=server_info&ip=212.200.163.182:27025 http://www.gametracker.rs (powered by LGSL)
I have intention to make it multilingual, but now it's only beta, and I want to finish all the features, then add languages ... http://www.gametracker.rs (powered by LGSL)
