I've seen several suggestions, and my favourite is still to require more than one DT1-vote to reach DT2, but I doubt there's a perfect solution.
Any change is better than what we have right now, but I don't see any real initiative for a change.
LoyceV is right, what you claim is completely contradictory. If we're talking about improving the forum, it's completely wrong to say, do something, and if I think it's good, I'll be a part of it. If all those who have the capacity to improve something are excluded, who can be expected to do it?
My opinion is not important, but if we do a vote I bet most of the members (including DT) would say that DT system is currently broken, but hey if you like it like it is now, enjoy.
Can it be improved? - Yes.
