There is an interesting project that can make ladders from custom maps:
https://wc3stats.com/The map must implement the W3MMD standard so the list of supported maps is a bit limited atm (check maps menu), the only map that is kinda played on our server is LTD.
Unfortunately the LTD versions played here seem to be outdated so step 1 would be to replace the map with a supported one. Then we could integrate with this service to create a LTD ladder and perhaps turn on autohosting. It can either be through their site or through API on our own web page (warden or w/e).
Is there any interest in any of the supported maps at all? I don't want to waste time integrating this if nobody uses it.
