A new pony fiction site has popped up! I have been following this one for a while now. It really is an impressive piece of coding.
The creator (You may know him from various projects like the custom graphics engine) has set it up as an alternative to Deviant Art/Google Docs/Fanfiction.net, with a bunch of bells and whistles missing from those sites.
It's currently in beta, and could use some testers.
Also Trixie. Not that this was the selling point or anything... Even if that is a really epic Trixie...
I will still be covering fanfiction as usual here, but feel free to send links from this site instead of the typical docs/da/fanfic.net trifecta.
You can find it here: Fimfiction
