I've been playing on and off for about 2 months.. LOVE IT.
I'm currently working on a heavy duty crane vehicle so I can move around some base modules that I have on Duna. After that I plan to mess around with the Kethane mod; maybe try to set up a fuel refinery on Minmus or something.
I haven't played much since 0.21 came out last week but I'll probably get on tonight now.
OP: Thanks for making the thread! I searched the forums a few weeks back but didn't see anything and got discouraged.
Edit: I caught this little video in the Squad weekly roundup. Good ol' Jeb.
