IF you recall from the mumble meeting a few weeks ago, those who are epic/pro rank in Classic will be given moderator priviliges in SMP, it's only a matter of time for Wooty and Ozy to get the coding down so those player only have mod access, and not total access to everything like Wooty or Ozy have. Obviously, the both of them are at E3 right now, having a blast, so it probably won't be until sometime towards the second half of the month at the earliest that will be implemented.
As far as how things are going in the server, I think it's a natural progression of things. People come and go, especially when it comes to gaming. New games will come out and distract players and cause them to ignore their previous games. I'm just as guilty of such a thing. I haven't touched my 360 in MONTHS since I found T9K and Minecraft. I think Wooty posted a thread about this a few months ago how minecraft is like any other game, and over time it will lose its attraction and people will move on. Whether those people move on to other games and drag other T9Kers with them, or if they just leave altogether is up to that individual.
