This is pretty interesting. I'm not quite sure how useful it is, but I like it. I've already found one erroneous link though. It thinks that Chief Petty Officer Burke that Jake met on Ajilon Prime and who died there is the same character as Lt. Maxwell Burke who was the first officer of the USS Equinox after it became stranded in the Delta Quadrant. I've already sent a message about it, so it may get corrected soon.
