Considering L4W only currently covers a range of about 7 levels that unfortunately means that most if not all judges are likely to have a character in range of an adventure submitted. This will be even more true if we implement 3rd characters. I think that answer must be that judges need to judge adventures they might play in.
Either that, or when adventures get submitted, judges should probably respond to the other judges wether they plan to review, plan to abstain, or simply do not have the time. That would make it clear to the other judges what's being looked at and possibly help delegate. It would be a shame if an adventure didn't get looked at by anyone because everyone had a character near that level.
Speaking of which, I know there was a call for new judges recently, but I'm not fully aware of the all the judges personal commitments. Do we think there is still a need for more?
