If anyone wants to stop in and chat (with us or each other) or just wants another IRC channel to idle in, the official IRC channel for Sins of a Solar Empire is accessible on irc.stardock.com, port 6667, channel #sins (if you have an IRC client that supports irc links, just click the link at the bottom of this post!).
If you don't have an IRC client already, Impulse has basic built-in IRC functionality. Just go to the Chat section under the Community tab, select #sins from the dropdown, and click Connect.
You can get Impulse here if you don't have it already. Just install it and log in with your account details from the forum here and you're good to go!
