A lot of people of suitable skill are back and play every day, or almost every day. At the very least: nnnils, Mythrandar, yellow_belly, Darkliath, Sharingan (Killer_Bee), Glagol (Steel_Spirit), seola_DMS, AntarestheKuuk, jakins, marchidanu, doggu, Quincrane, Rin, reggird, Invisible_XXV, gazcrowbar, visca_el_barca, IN1.
There are a lot of people that don't play every day, but whom I still see several times a week (like KALEL or Soccer_Mom), and there are some players that I can't really say are the same level (i. e. they can't fight nnnils, for example), yet they are pretty darn good, still (Pureriff, MegaAnt, cartman, etc.).
Given the high number of skilled regulars, maybe there is a possibility to conduct a 2v2 tourney? I'd keep the rules as simple as possible: single elimination, any DGs, no doubles, but the sum of DGs each team uses must be 4 points or less (as per the 2010 3v3 tourney: UB, Oak, Erb, Rook = 3; Sed, Occ, QoT, TB = 2; Reg, DA = 1).
