There is no secret to getting a multiaccount (multi :P), it's as easy as 123: just make a new account and play. What most players aren't bothering with is brainstorming about how are admins able to track your multiple accounts.
So, lets start with the basics of 'privacy'.
Admins (GO's or game operators, or game admins, take a pick) can connect your in-game account with your forum account - not just with IP, but also with cookies. Most users don't ever bother deleting cookies, even if they do know about them.
If you're using Firefox, you can delete them by going to Tools > Options > Privacy > Cookies, and press the Clear cookies now button. In Internet Explorer: Tools > Internet Options > Delete cookies button. For Opera users, Tools > Preferences > Advanced > Cookies > Manage cookies.
Next step is hiding your IP address. You can view your IP adress on this page.
Usually, reconnecting or reseting your modem does the trick, but if your ISP is always providing you with a static IP that won't work. Sure, you can play with more account on the same IP address, but you want to 'play it safe'.
What you need in that case - or in case you don't want to reconnect all the time like me - is a proxy server.
From wikipedia:I hope you understand now what a proxy server is, cause I'm not explaining it further. What you need to know is how to set up your browser to connect to one.
A proxy server is a computer that offers a computer network service to allow clients to make indirect network connections to other network services. A client connects to the proxy server, then requests a connection, file, or other resource available on a different server. The proxy provides the resource either by connecting to the specified server or by serving it from a cache.
So, let's say you're using Firefox to surf websites, play Ogame, watch porn etc. You can set up IE or Opera to connect through a proxy server. Why use two browsers you might ask - well, you can then be logged in with two accounts, with different IP adresses and cookies. If a certain site, in this case Ogame, sets up a cookie in Firefox, that cookie won't be seen (shared) with IE or Opera or other browsers. It saves you the trouble of deleting your cookies all the time, and there's no way admins can connect both of your accounts.
Just don't do the obvious: don't send resources to your main account (usually higher ranked), that's pushing. But you can set up colonies in your system and farm your multi when needed. Just play like a noob and you'll be ok :)
Just imagine the possibilities: your system can be full with your multiaccount's colonies - nobody can 'move in' to recycle you, and the best part is, you can farm yourself as much as you want to. If there's still free colony spots, just make another multi :D
Ok, now the tech part, setting up your browser to connect through a proxy server.
It's fairly simple, I'll explain how to do it in Opera. If you want to use some other browser for your multiaccount, just digg a bit in options.
In Opera, go to Tools > Preferences, select Advanced tab, find Network and click on Proxy servers button. Check HTTP checkbox, and input your favorite proxy server's IP address and port. Leave the rest empty it's not important, unless you know what you're doing.
If you don't have a favorite proxy server, you can do a Google search and you will find lists with plenty of them. Some might not work but it won't take long to find one. If you're really having trouble finding one, you can check this list.
After you set it up, don't forget to check your IP address again just to make sure everything is allright.
And, one more thing to mention - don't login to your forum account from both browsers.

That's enough for today's lesson, happy Ogaming :)
