I hope there's one soon, but if not, I can wait.
The fact is that MarkT has - apparently - had oppurtunities to hand the stewardship over and is not blameless.
Just to add an unrealistic and inapplicable analogy to add weight to my argument - you say Mark is a volunteer, I agree. However in my town we have volunteer firemen, if they were busy for a few months when a house was on fire I imagine the town would burn down, hardly desirable.
Thusly - without actions figures - I hope to have demnostrated that even though a position maybe voluntary and is without pay, it is not without responsibility. So please stop saying MarkT is blameless.
Although compared to former archivers he is still by far the best. The system that he has implemented is great and certainly he has done a great deal to help but quite why he has insisted that he retain control when he could have passed it on is beyond me.
