Welcome Eliteus (may I call you Eli?), to Wintreath!
I hope you're enjoying our community, or what you've seen of it so far.
The basic run down of NationStates (NS for short) is that you manage a country by solving issues given to you every twelve hours, at the updates. Other 'vanilla' game aspects include voting on WA debates and participating in the Regional Message Board of the region on the NS website.
A quick FAQ of NS is on their website:

You can participate in our regional government by talking at the Citizen's podium subforum and if the people like you enough and you choose to run for Underhusen in April, you might get elected

You can, if you are interested, join our military at
http://wintreath.com/forums/index.php?topic=56.0And there's always the General Discussion's forum for just about anything.
On our IRC channel (under the Chat tab, or if you have a client already irc.esper.net server, #wintreath) you can chat with us and we can get to know you better, a valuable tool if you want to get elected.
I hope you'll stick around and welcome once more!
