Well your game server does not hand out the custom maps to your players very well. Very slow speed can take up to 30 minutes to get some of the big maps. As well as your mod would be hosted there so your players get the files they need to join your server fast and easy.So you get a redirect there's one at the bottom of this post. just one there are hundreds. Not to much money as well . Its also more than likely the game server host your using has a redirect for you. And do not be sorry we were all where you were once. If you pm me with your ftp creds I can help you right in the server files instead of telling you here. That way I can find the problem and then let you know how to fix it.
p.s. also need TS addy
