Heh...okay. I didn't have a problem up until you said I didn't have the right. Especially about sharing it with personal friends. That bothers me. First ammendment, lady. And people put their ideas out for the whole world to see. I don't see the harm in expanding on that idea, especially if:
I put a disclaimer at the beginning of every chapter.
I don't make chicken scratch doing it.
I honestly don't see how I don't have the right to have fun if it doesn't. hurt. anybody.
Why is this such a contraversial issue? Nobody. Makes. Money. It's. Something. That's. Enjoyed. Need I spell it out more clearly for you?

A few hopefully *not* too spoilery details: my main character has somewhat recently converted (a year or two) to being a Jehovah's Witness, and since her faith -- which she loves dearly, since it's given her a sense of purpose and community -- does not allow blood transfusions or anything like it, she has to decide between following the tenets of her faith to the letter and wind up dying, or adjusting her beliefs to fit her new state of being and risk being shunned by others in her faith community. The idea came to me when I was watching a short PBS documentary on Jehovah's Witnesses, much of which dealt with the case of a young man who needed a liver transplant and the challenges he was facing because of it, since the surgery would require him to have a transfusion... and I'd recently been watching episodes of the anime "Hellsing", thus my strange brain came up with the question, "What would someone who's Jehovah's Witness do if they got turned by a vampire?" It was a loopy idea at first, but as I started quiddling with it, the story started to take shape and acquire a much more serious note.

But how in the world does it figure into a drive?  I know what a Moebius strip is.  a three dimensional object with only one side...  but drive?  LOL

dilithium crystals -- We already use lithium for energy, so TOS was ahead of the curve with this.  Gene Roddenberry was interested in having plausible science, if not possible.  In TNG they've moved up to trilithium crystals.
I have long held a theory that the reason that everyone in TNG is so laid back is because the lithium leaks out of the engines and bonds withtheir blood, and so they all are on lithium....  *g*

Where is Mobius Drive from?  I can't place it off hand.  Maybe it is just named after a guy named Mobius? 

I disagree, deeply and profoundly.
Yes, you need good characters, but if good characters are all it takes to tell your story, then it does not need to be SF.  Good SF also needs ideas, the best of it are things that could not happen in a contemporary mundane setting and human reactions that also could not happen.  Sometimes even the plots could not happen.

Fanfic is like anything else in the world - dependent on the person behind it. Unfortunately, we have a rather large amount of stupid in the world, so the vast majority of the people behind it are going to show through badly.
