Welcome to BB! 🙂 Everyone is very nice here, so I'm sure you'll make some new friends. 🙂
We mostly just talk about Buffy, and also Angel and other Joss Whedon stuff. If you're a fan of Buffy, then you're in the right place for sure. 🙂 Just take a look around and post on whatever you'd like. The forums are categorized on the main page so if you want to talk about a specific season of Buffy, then click on the boards titled; Season 1, Season 2, etc. If you want to talk about the show in General, check out the board titled 'Inside Out'.
There's also a lot of other boards to check out, and they all have explanations below them explaining what is on the board. Have fun! 🙂
