Actually, you'd need to PM them to me. I run the Kustom Kettle server, and thus handle the custom maps around here, and prefer to review anything before it launches.
Please be aware, that custom maps need to have a level of quality that is similar to that of the stock maps. That takes considerable time, effort, and skill. This means that not only must they look professional, but they need to play well, and be accurately balanced. It takes a LOT of time....
