+## Concept
+Usually, whenever you have multiple classes with similar code, you would inherit one from the other, or both from a common ancestor. Currently, AccountManager and CharacterManager (and hopefully RoomManager) share all of their method names, so ideally I'd write an interface class. However, since each requires a different number of parameters to some of these methods, I can't do that. Instead, I'll list the methods here.
+
+## Common *Manager Methods
+An ellipsis (...) indicates a list of variable parameter types, and T is the type handled by the manager class.
+
+```
+//basic management methods
+Create(...)
+Load(...)
+Save(int uid)
+Unload(int uid)
+Delete(int uid)
+UnloadAll()
+UnloadIf(std::function<bool(std::pair<int, T>)> fn)
+
+//accessors
+T* Get(int uid)
+int GetLoadedCount() //number of elements in memory
+int GetTotalCount() //number of elements in database
+std::map<int, T>* GetContainer() //OO Breaker, I couldn't fix this :(
+
+//database hooks
+sqlite3* SetDatabase(sqlite3* db);
+sqlite3* GetDatabase();
+
+//The constructor & destructor are default, and private
+//The singleton template class is declared friend
+```
+
+## Theoretical Solution
+The only technical drawbacks are the parameter lists of Create() and Load(). Otherwise, a templated *Manager class is perfectly viable. Here's my outline for it.
+
+```
+template<typename T>
+class Manager : public Singleton<Manager<T>> {
+public:
+    //list all above methods as virtual except Create() & Load()
+    //some methods, particularly those requiring database access, are declared pure virtual
+private:
+    std::map<int, T> container;
+    //etc.
+};
+```
+There's no guarantee this would be 100% perfect, since the RoomManager class will likely require other systems, like room management, etc. Nonetheless, this is still an OK template to follow.
