Oh, yes, please do! Your writing is excellent. I think you're one of the best writers I've read - not just in fan fiction, in everything. And I'm not saying that to massage your ego or anything. It's just true. So don't hide it away! Post it!
Did you read that 'Shelter' Story? What did you think? I'm not too sure about it really. It's a bit (ok, more than a bit!) angsty and silly!
