Laura, All About Spike is one of the strongest and diverse archives on the net. Kudos to you for screen all the fic and really maintaining such a high standard. Honestly, I didn't know you could submit. I thought it was by invite only. (needless to say I was tickled when you asked to archive my stuff)

Anyhow, you get to run it however you want. That's the beauty of being the sole archivist. And, seriously, you don't need a long winded letter explaining your rejections. Don't let people make you feel bad for your decisions. Stick to your guns, sunshine!
