I'm sort of new here, so maybe I should stay out of it, but I agree with Mal about stricter guidelines for a 3rd PC if they're going to be allowed.
I understand about there being a lot of adventures and not as many PCs right now. I also understand the argument that if new people do wander in, you don't want them to have to wait around too long for an adventure (because of PC shortage or otherwise) or else they might just as easily wander away again. However, I also see that the current judges are already seeming a bit overburdened and allowing 3rd PCs is only going to add to that burden. If there are tougher requirements to get that 3rd PC it will lessen that burden a bit.
I also think it might be helpful if more judges were added before 3rd PCs were allowed, as that would also lessen the burden on each individual judge and make it easier to accommodate the workload that approving 3rd PCs would add. However, that requires qualified people volunteering for the job, which I would suppose hasn't happened or the current judges would have jumped on the chance to share the workload already.
