My advice:
a) There should be a master editor who is responsible for proofing all the transcripts before they get submitted to a Admin for upload. This master editor can keep the transcripts uniform-looking in their formatting and grammar and syntax, since different people will transcribe in different ways. (Some people go crazy with too many commas, some people want to include every last "uh" and "um," some people are too generous with em-dashes and parentheses, etc.) Also the master editor can make sure the transcriber got each and every technical word correct, like all the names of and numeric designations of and calibers for different guns, or the correct spelling of a guest's name, or the correct way to format the call numbers of a House Resolution that is about to be voted upon in Congress, or the correct name of a town that comes up in the news, etc.
b) I also think that a VERY expanded version of "Show Notes" should be included on Page One of each transcript. The expanded version would be more than just the links to this and that around the web, but even a dry list of every unique word mentioned in the podcast. By "unique word" I mean the exact name/caliber of a gun, or the exact name of a person from history that Jack mentions during the podcast (like Thomas Jefferson or Fibonacci), or the exact name of a web hosting site Jack names as a very cool site to do business with (like Host Gator), or the exact name of a huge corporation (like Monsanto). That way, Page One can serve as an at-a-glance guide to the contents of each transcript.
c) I think that a sub-forum for housing the transcripts here would be awesome. But perhaps that sub-forum should be read-only, or else maybe it should be restricted in such a way that only admins can start new threads, but regular posters are still allowed to post in those already-started threads. That way, the admins can control the wording of the thread titles so that they titles are all uniform with each other like a card catalog.
Just my suggestions.
