Hey there, I'm new to the PZ Server scene and I'm building my own and thinking of adding some mods. I tried looking for one but couldn't find any, Can we get a splash screen mod? Like for example, when someone joins the server, a text screen or image shows up on the screen that a user can click "x" on to close? It feels like it would be so simple to create and I'm surprised no one has done this yet (or maybe I'm just not good at using the fourms). Thanks!
