Not to be a total downer, but I'm not so sure how popular this idea will be when people can log onto FanFiction.net and read to their heart's content.
This is a totally honest question and I'm just curious. What is going to make you guys more appealing than that to our con goers?
Hmmm, well, I'm thinking more than people would like to read to their hearts content on Fanfiction.net, but also, readers love the book in their hands, as well as people will always shop at Artist Alley and seeing fanfiction will make them want to buy it. (I mean, I've seen it a lot. You can buy shirts with silly slogans online for like 15 bucks (Probably the same shirt too) but when people are shopping in some place with rows of sellers, they just want to buy it right there and then because they can) Of course, this will not apply to all people, but seeing as this group doesn't plan on producing all the fanfiction onto the internet, since it's a new story, if people are interested they would have to purchase it at the stand. I know this doesn't make it any more appealing than fanfiction.net, but I already knew that that would be a factor.
Also, I usually include certain special factors in my fanfictions, like for YuGiOh, I'll include the decks for those interested, or how the story was made, or other specials. Usually most won't consider doing this in fanfiction.
Finally, I'm debating about whether to do some illustrations at different points in the fanfics. This is another unique item since fanfic writers don't use drawings as well.
I hopefully answered your question and hope that you allow us to sell our fanfics at NDK
