Once you get the map ready, make sure to test it on a dedicated server to make sure the sounds still work. You either need to pakrat the custom sounds into the BSP or include the sound files themselves in the download (in the correct directory structure). I forget now exactly what I did, but in 2mesa3_classic, I forgot to include the alarm bell sound so the help button doesn't play anything. It worked when I tested on a listen server but it stopped working on a dedicated server.
