It's basically an editor.
You send me chapters before you post them and I go and fix the errors and send them back to you.
I've never offered to beta for someone before, but if you don't want me to, it's fine. Just thought I'd offer.
Well the ceiling of course! And the sky above that! I love your writing, even though I don't write much fanfiction myself. I do love to write though, just my own stuff, maybe I'll post some on here. Anyways, what's up with you?
