If I had a fan fic that wasn't about fallout, could I still post it?
Well, is it loosely related or inspired by? If not then I'd guess no. But if you activate comments on your profile, then people who want to read it can ask you for it.
In any case, EnclaveRulez, all I can suggest is that you put a link to your story in your signature. If it is noticable enough, I imagine people will give it a look.
Not sure if it's allowed to post about other sites so i'll remove it if told to but
Spoiler
Fanfiction dot com has a game section that has a Fallout section.
It's dot net. But, now I wish I hadn't gone and browsed the Fallout section over there :wacko: Crossovers can sometimes be a good read (I've a few excellent ones saved from years ago) but it's hard to find the good ones amongst all the average ones.
