Rather than trying to teach people your way, teach them the right way, and let them choose to do it your way instead if it works for them. Otherwise "No means no".
If you are confused about the language, then D&D probably isn't the best place to learn it. Buy a dictionary instead of a splatbook.
DM: There will be no Tiefling PCs.
Player: I am curious, why?
Besides, if I included every Why, do you have any idea how big my ad would have to be?
I think many see D&D as only a reason to get together and have "beer and pretzels", so the non-game elements are more important to them, wherein others actually want to play a game.
Some want a game, while others want a book group or soemthing.
While I harbor no ill will towards "casual gamers", it's not my thing. I'm running a game to play a game. If I just want to eat and shoot the bull, I wouldn't be setting up a game at all. Game time is game time, beer and pretzel time is beer and pretzel time. For me, never the twain shall meet.
I wonder how many of the people posting in the interest of "communication" thus far have been the casual gamer type versus those that are interested in gaming for the game?
Back to my original example restrictions, beyond being in my mind the Borg of fantasy materials, I dislike super metals because unless I'm playing something like the Ratchet & Clank video games (where gratutiously unnecessary firepower is the point), I want your character to be special by his personality, skills, and such. Not his Infinity+1 swords.
