The Two Commandments of Trekkism:
1. Thou shalt watch Star Trek.
Consuming Trek entertainment in other forms — books, comics, games, soundtracks, paraphernalia, etc. — is also encouraged.
2. Thou shalt share thy love of Trek with others.
Watch it with friends and family, or discuss it with them. Attending conventions and making new friends through Star Trek is especially praiseworthy. If you're a shut-in with no friends, you can still follow this commandment here on TrekBBS — kind of a cop-out, but at least it's something.
