When nobody else in your FC is online or just don't want to join you, you can always just join someone else looking for players in PF, which I'm sure people will do...

That being said, what kind of FC's are you all in, where there always are people online? In the evening, sure, there should be people online... but if you come online in the morning on a weekday, are there really always gonna be someone online in your FC's?
