A "mundane" meeting of people who are in the scene. As I understand, they meet at a coffeehouse or such, just to talk and meet new people. You do NOT dress up for this-you want to stay under the Muggle radar. I have not been to one yet, combo of time, courage and knowledge issues-but I have heard good things from people who have gone.
Stay with us on the Library-I have learned a lot since I joined, even if I didn't get to practice much of it, yet. Good Luck!
