Spring RTS Engine

how do i get to the area where i would mod stuff and/or make a game.

ok so how do i download one? Said something about Spring downloader...but i already downloaded spring...

Edit:

figured this part out

well I though a server setup would = a battle setup for whatever game i get going.

And how much can the master server handle? is there any type of limit? and also, what type of poly count should i stick to?

So if I make my own game I dont have to code the network or pay for a server? Liek i said i CANNOT use my home network for any type of bandwidwth consumption or a server because of hackers etc.

OK, So is there some type of GUI for the engine or something or is it all coding? And I'm still confused with the lobby thing. I want to make a Multiplayer game but I dont want to use my home network. I want to use something like smartfox (http://www.smartfoxserver.com/products/basic.php) or RakNet ...

Hey, I just downloaded spring and Im VERY confused. Is this an RTS engine or a gaming platform? Is it for modders or developers? Whats this lobby thing? Does it give acces to theyre servers if I make a game or does it suck up my home network for a server? And if I have to setup something like SmartF...
