Last plug here. First off, come to our site: http://www.explorminate.com. It's a site meant to rally the community in to one central spot, where everyone is invited to participate and contribute.
We recently started a Steam group that ALL 4X and 4X-lite fans are invited to. Find it here: STEAM GROUP
Secondly, we have a YouTube channel (that most of you have probably seen) with Let's Plays and the like, here: YOUTUBE CHANNEL
Lastly, we have a Podcast that just started today: PODCAST
Please come out and join in. We're a large community and it would be awesome to see us all get together, do Let's Plays together, Podcasts together, and writing about our favorite genre: 4X!
