I can answer questions about the Enterprise, her crew, and the alien races which frequented the show. I've watched every episode, some several times, so I can answer many questions about plot, characters, or other things you'd like to throw at me! I can't answer questions about the other 4 Star Trek series. I can try, but my knowledge of those series is not as great as my TNG expertise. I also cannot answer questions about the 'behind the scenes' of the show: the show's production, the actors/actresses, etc. I know the names of the actors but that's about it!
Star Trek fan for about 20 years; used to record/watch episodes on VHS until the VCR went the way of the Husnock.
Fan of the show; I learn from watching and hearing the input of others.
