I guess problems with the host of the site. If the galciv forums were more active, this thread should be posted in the empires forum. But I guess that the empires forum is more inactive than this one.
For those who doesn't know about it, the Galactic Core (www.diplomats-empire.com) is a site that was created by Galciv players (the Diplomats empire whose members can be found in the IBH empire and the All good things empire). But Galciv isn't the only topic discussed
