There are two pieces of information that need to persist between sessions: the number of characters the addon has met, and whether it has met any particular character. To save the count, a global variable, HaveWeMetCount is used (and saved on a per-account basis through #SavedVariables); while HaveWeMetBool is saved per-character and used to determine whether the addon has seen ''this'' character before. | There are two pieces of information that need to persist between sessions: the number of characters the addon has met, and whether it has met any particular character.
