I don't pretend to have much Sins of a Solar Empire experience. Hell, I don't even own the game, I just play it at my friends when I get the chance. I've only actually played one game against the Normal CPU.I do however, plan on buying the game as soon as I get some funding freed up.
But what I do have experience in is forum management. I am the founder, and admin of www.sporemods.org, the most active Spore forum(aside from the offical forums), and the only Spore Modding forum.
What else do I have at my disposal? Web hosting, money for a domain, and a Vbulletin liscence. Vbulletin is the absolute best forum script on the market, but it's not free.
Edit: I've set up a forum. Right now it's pretty out of the box as far as addons go, and the logo is some 5 minute thing I did in photoshop(the text, the planets are part of the forum style).
I'm not buying a domain quite yet, but I'll use my host's provided subdomain: http://eusa.flatlinevision.com/forums/index.php
