1. The Sorting Hat - This account is used to sort students into their houses.

2. Cousin Skeeter - This account is used to generally fill in the gaps, play the storyteller / narrator, etc. Cousin Skeeter can also be a specific person to help move along a thread (a random member of authority, etc) or can be a person interrupting a thread or causing chaos (e.g. a streaker!) You can request Cousin Skeeter to spice up a thread if you like, or he may just butt in!

3. Nicomedes Daegon - A Daily Prophet reporter since the early 1970s, he's very well-known and respected in wizarding Britain as a reliable source. Not much is known about his personal life, and he's done a good job covering it up through the years. Nicomedes generally posts Daily Prophet articles here, but he can also turn up in a thread as the British press.
