There's a new GB Meme running now in LJ. It's the Get Backers Anonymous (Kink) Meme. The good part is that it can be both fanfic/fanart and kink/no-kink (which means there's much more than plain simple sexy action); plus all posts are anonymous so people from outside LiveJournal can also participate. There are some cool entries already.
Here's the link: The Get Backers Anonymous (kink) Meme
Some posts are not proper for young readers so DON'T GO if you're underage.
If you are old enough, wonderful! Go there, make a fanfic/fanart request or respond to one of the request posted. Or, simply go there and enjoy the cool shortfics already posted.
