Heya!
1. Nope! As long as you, yourself, only have one alias, that's all we care about. The one alias rule exists to prevent people from abusing our character restrictions. We figure it out if somebody is lying anyway so as long as you and your roommate really are two separate people, you have nothing to worry about. <3

2. We don't use discord for site things because we have a Cbox. So you can always poke the Cbox or you can pm an admin after you join with questions. Or you can post in this forum. We prefer to keep things on the site. Other individual members might have discord for plotting purposes with others but we do not have and will not have a server for the site.

3. Your character can join the Order or Mortenero anytime if they are the right age and it fits them to be in that group. You can register your character already being a member, if that's what you wish, or you can plot to have somebody invite them into the group. It's up to you!

4. You can but most of your threads would be owl post threads or holiday/summer threads in the form of flashbacks because otherwise, they're at school. So it does create limited plots unless there are no other students at that school. -nod- But it's not impossible to have plots. But as long as you aren't attending Beauxbatons and trying to post at Hogwarts, it can work out!
