Hi, I am only going to give you some most basic info to get you
started, and I am sure someone more experienced than me will post with
more useful info in response to your post, so check again soon.
The site which you should visit for all kinds of information about
empire is
http://www.wolfpackempire.com . You will find there all the
basic info to start playing. There is also information about new games
starting, but as far as I know not all the games are announced there,
so you should also check this newsgroup for game announcements. On the
wolfpack site you will also find links to the games which are
automatically restarting periodically, zebra and changeling blitz, and
I think changeling game is the best way to get familiar with the game
mechanics, but I strongly recommend that you should first read a little
bit on the wolfpack page. Another site which you might visit is :
http://www.angelfire.com/empire2/bungholio/empire_games.html
There are hints for new players how to organize the country during the
first few updates, and also some graphical record of a few the games
played in the past.
I have to go now, but I will try to write here again soon, and give you
the bare minimum info about the commands you should be familiar with
before you start playing, otherwise you might be a little confused at
first. In particular I will give you some hints (although from a
relatively inexperienced player) about how to organize your country, so
that it will relatively smoothly run during those hours when you are
not around. I will also start playing the Changeling game after the new
year's eve under the name of Sarmatia, so if you start playing there
(but not until the new year's eve, because the old changeling game will
be still running until sunday I think), use the "anno" command to ask
any questions, and I will frequently log in to the game and try to give
you answers to any questions as soon as possible. Hopefully a few more
experienced players might start their countries too, or at least login
as visitors to answer your questions when I take a break for the
night:) In the game I will also play my country in such a way, that you
will have a chance to practice attacking and defending. I hope that a
few other ppl will start their countries in changeling, even running
their countries very inefficiently and infrequently, because it would
give you the chance for even more practice. Anyone?

The command to
ask questions in the game, by the way, is "anno". The command to check
if there are any replies is "wire".
Before you do anything else, you need to get your empire client (either
compiled, or in the binary form), so the start for you would be
probably to try to get that client to work by connecting to the
changeling or zebra game currently running, and see if you can login.
If it doesnt work, post here about your problems and someone for sure
will try to help you.
Hope to see you in the changeling game (or another newbie game, if it
is announced soon).
And don't get too easily discouraged, because if you are looking for a
really challenging, addictive wargame, you just found it, and it is
worth all the effort to get started!!!
