Welcome to the forum, Dragonkin! Nice to meet you.
A rundown on furry culture? That's a big question, and I'm probably not the best person to answer it, but here goes. We like anthropomorphic animal characters, so let's start there. Even though we're called "furries," there's fair number of reptiles, dragons, birds, and some other creatures. There's lots of art and writing, and some role playing. And most of the people are friendly and accepting. That's the most important stuff, I think.
