Well, I did start out in the Civ forums (someone at an RPG forum recommended CFC for information about Civ II - back around January or so of 2005). I lurked here and there, posted a bit in Civs II, III, and IV, and eventually noticed the Colosseum. I still read the ToT threads and post occasionally there, but OT and A&E are my main haunts, along with a couple of the social groups.
And yeah, ten years seems like ages. Aside from Yahoo!, it's the site I've stuck with the longest since I've been online. Only a couple of gaming forums and a Doctor Who forum come close, and my tenth anniversaries of those places will either be later this year, or next year.
If nothing else, my legacy to CFC will be the :mad santa: smiley.
