As a normal character, you wouldn't have to worry much about the journal or the tagging system unless you plan to potentially run a game. :Bb

An example is, say, a Personae wants to run a game that has different posts locked to each team for the game duration. They could use the dramatispersonae journal for game-related things instead of making 7 locked posts on the main community (...if that's even possible to do on a community journal?).
