Thanks for the welcome. My girlfriend Mari and I also run a grim and gritty-type supers game in the Freedom City setting called Freedom After Dark at
http://z8.invisionfree.com/Freedom_After_Dark , and we also play a really cool D&D game called Waterdeep: City of Splendors. Don't have the link on the top of my head.
As for my experience, I've been playing RPGs for 18 years now (I'm 26, so you do the math), and pbems for about a decade. I mostly DM/ST/GM because, well, I've a lot going on in my brain meats.
