TF2 Loading page - Thankyou Rasczak for supporting this map - List all connected supporters.
It would be really nice to see who all supported this map from the players connected to server.
Hello @anttiryt, sorry, but this isn't coherent. If this is about the map makers, this request would need a structured way to programmatically get credits from the map files. If this is about supporters for a third party community server, that's not something a Source engine dev would provide, instead, it would be some kind of server mod.
This is likely about the 'Thank you [username] for supporting this map!' message on the loading screen. The request here is to list all players connected to the server that have bought a map stamp for it.
