Here are my nominations:
Jim McNaney - Tier 1 SWM organizer. A critical member of the PA/MD playgroup. Also now a long-time host of the SHNN, and a solid volunteer for GenCon (when he isn't stealing some kid's Teddy Grahams
). Add all that to an all-around awesome guy who makes the community better just by his presence. He is involved in all those important discussions when we try to figure out where the game is going or where we want it to go, and always gives valuable input. This guy should be a shoe-in to the HoF.
David Weeks - Tier 1 SWM player. Also heavily involved in v-sets, major playtester as well as designer now. 2-time top 8 player at GenCon, just won Minis Mania 2, has a few regional wins under his belt. Regular contributor to the SHNN.
Graham Bingham - Another tier 1 SWM player. Has a ton of regional wins, I believe second only to Tim. Big time playtester, and a valuable asset to the design team. Member of the Playtesting Committee. He's one of the guys who is absolutely dedicated to the game.
Swinefeld - As The_Hutts mentioned, he's one of the key pillars of Bloomilk. Great all-around contributor to the community. Current curator of Mini Manager, one of the best resources for the game.
The_Hutts - We need not forget our oversees playgroups, and as far as I can tell, The_Hutts is one of (if not the) best players of the NZ group. Won plenty of tournaments down there, proving that he's one of the elite players of the game. He's also a big contributor in pretty much all discussions on the forums, and a major squad builder.
