Oz is the big man, but his real life prevents him from doing a lot atm. So Winbrian is your main goto guy. He can always help out.
Strac knows a lot about pvp and toon setup, and it's always nice to have a soundboard to talk about your ideas of char development (at least I have liked those few talks that we had)
Me I'm trying to attend as much sma meetings as possible, I follow up the SMA forums, I have been updating the corporation fittings. Generally just helping out where I can.
I'm also (and since a few months Winbrian as well-) a part of the SMA Market Office, we stock monkey space with jita goods so that we can fly our doctrine ships decently. I also keep good relations with both Hrabandur and Khujo. Hrab is an SSX director (or however it's called) and khuj is either well on his way to become one, or he already is one
That's more or less it
