Thanks as well. I was familiar with a few of these already but a couple of them are new to me.
I've read some of Colony Drop, but the operators seem a bit salty regarding new anime for my taste. Yeah, it's true that I prefer mostly older anime to the newer stuff but I don't HATE the newer stuff. Besides, they haven't updated in two years, it seems.
Even though the forums there aren't amazingly active, there is the
Old School Otaku Lounge. It's not an extremely happenin' place, but it's got some conversations going on. They don't get a ton of people joining so it takes a week or two to process your registration but overall, its a nice place and most of the people there are rather easygoing.
