Hi everyone, I’m finally giving up my three months of lurking to take part in the forum. I’m not really sure how I found the site, but I kept coming back for information and then to read the discussions and fan theories. I have to admit, I have only seen the reboot, the original series was before my time. It’s nice to meet you all. 
Welcome and you might be able to rent some of the original series episodes from you local library.
Also, feel free to join in the fun with trivia and quote guessing games.
