When checking out a new server and FC, I suggest a week as a good stretch of time to get to know people and their schedules. If you log in one day when people are super silly or maybe sad over something or pretty much just quiet and keeping to themselves, that does not give you an overview; it just gives you a snapshot of 'right then' in that FC. I'll allow that it will color your judgment for the future. We're human, can't avoid that. But being patient and checking out a new home for at least a handful of days will reward you with a better idea of whether they are right for you and may be just what you are looking for in a FC. ^^
