There is this pretty cool episode guide timeline that just came out. Let me know what you think. Star Trek TOS timeline They also have timelines for the other series, but they aren't done yet...
Thanks -- I hope other people like the link. Yeah, my friend is a big fan and he made the timeline. He also made one based on events in the Star Trek universe (he took the data from another site), but that's a little more complicated. http://xtimeline.com/entertainment/TIMELINE-OF-STAR-TREK-HISTORY-1 It's got events in there from the novels and from RPG supplements. I'm not sure how much of that can be considered canonical. Anyway I hope people find it interesting.
The timeline linked to in the thread-starter, http://xtimeline.com/entertainment/Star-Trek-Production-Timeline is messed up. For starters, it's called the "Production Timeline", but it puts CAGE first, followed by MAN TRAP. It shows the original "Pike" pilot as the first episode, then jumps to the airing order. It's all messed up and someone got confused. Not for public distribution, in my opinion. Sorry, but it's so messed up this has to be said.
I have to second that. While the individual episode entries with summaries are very nicely done, the board seriously misadvertises itself by calling itself a production timeline, as the episodes are all in airdate order and the dates given for each one are air dates, not production dates.
