MarieNomad, first of all: it's great to see that you've found your way to the fanfic section, it's nice to see a newbie with some ideas for fanfiction! 🙂
You're more than welcome to post ideas here, but we do ask that you try and keep it to one thread (just for organization's sake, your original thread looks like it'll work great to get feedback!) and try to remember to "flush out" your ideas a little bit. The more you explain a fanfic idea, the more people can understand the story you've imagined and then they can give their thoughts on it properly (or use it, as the case may be!).
And as this is a family board, please be sure keep all fanfic and fanfic ideas family-friendly (no R or NC-17 rated fics).
I know it's a lot to get your head around, so if you have any questions about posting please feel free to send me a PM. :thumbsup:
