Kayo Dot, some of the random unofficial forums, Hypocrisy, GMD, and then the old Opeth forum which I don't think even exists anymore. Not a whole lot at any of those places though, at least I don't think. I'd guess 95% of my madness is at RC.
Plus I triple post a lot, whenever I'm actually here to poop/post. And did y'all forget some of those drunk threads I did back in the day with like 20 posts in a row talking to myself? One night I literally made a thread with each post being the lyrics to a different Danzig song. Then I PM'd 2/3rds of the board and said "READ THIS, IT'S VERY IMPORTANT!!!" and then woke up the next morning with a wicked shame-over at my own foolishness.
Seriously though, I drank far too much back then. Shit, I drink far too much now, and it pales to what I consumed in my early 20s. There is a reason I was so fucking fat back then, it was mostly liquid! Bloated NAD, bloviated buoyancy.
