I just have a simple question, does anyone know if it's possible to send a Steam Message via an in-game command? I want it to be automated that basically will send a message to all of the registered Admins of a server that basically says something like: "xx has called for an Admin. If you can, please get on and use !calladmin_handle x to let other Admins know it's been handled." I saw something like this in a CS:GO server, but I was wondering if it would be possible via LUA? If so, anyone know how?
TL;DR: Can you send a Steam Message to someone with LUA?
