Welcome, Dude!
Only guy currently posting on the boards with any frequency to my knowledge who was also active on SedFast is
DrexelScott, who was ChitownMaverick until he had a falling out with the management over there and they banned him.
Teevster (TVA_Oslo if you were on mASF) is
Alek Rolstad here, though he mostly sticks to articles and only ventured on the boards but briefly.
JWS has not joined the forum at this point - I think he expressed interest in it originally, but, you know, inertia... tough getting started with a new place.
TheCostOfSuccess / Cosy also writes here, as Cody Lyans, as does Darius Belejevas, who I think is David K. over on SedFast. Like Joseph and Alek, only articles though, not on the boards.
I think that's all the guys who are on SedFast. If you want to check out their articles (most guys respond to comments on their own pieces, so you can still engage with them there if they aren't on the boards), here's a directory:

We also have a slew of talented members on here that post up lots of field reports and lay reports and insights... check out the member list by rank for a quick who's-who of the more advanced members - of these, J.J. (NarrowJ) and Hector (Anatman) contribute articles fairly regularly:

The board's still "new" and our first generation guys haven't reached the point where they're experimenting a lot with relationships, so you won't see as deep relationship tech / conversation as you'd have seen on mASF and I presume on SedFast, but it'll get there... once the first generation of guys starts running mLTRs and stuff like this that board will probably get pretty fun.
