The posts to the community are written by two people, but all are welcome to comment. The stuff they are writing is hilarious! If you like the Harry Potter characters, you might very well enjoy this. I think they're up to 13 or 14 installments, now. I have friended it to my musevoices journal.
Warning: It appears to feature a developing Remus/Sirius relationship, and some people might not care for that. The story is still very amusing, though. :)
