Fleet Channel, named fleets channels and no Starforce channel

[Celarious]

especially if they wouldn't normally respond outside of a fleet due to not having an officer

Ships don't require an officer to be part of a fleet? You sure about that? Interesting if true.
Yeah, then it just makes even more sense. Not sure they would reply if you hail the Fleet channel either then.

Yeah I tested, any ship can join, I added everything in orbit over my capital to it no problem
