Type these in your server's Console card to see who is online, message everyone, kick and ban, change the map, change a setting for now and run Lua. With ULX on your server, its commands work here too. No / needed, and capital letters don't matter.
Open your server in My Servers, type in the Console card's command box and press Enter. Your server must be online. Swap the made-up names, numbers and messages in the examples for your own. To stop or restart, use the Power buttons.
