I'm communicative to a fault, I'm always talking to my crew and encouraging them to type something or say something back, even providing instructions on how to do both if I get no response. If I never get a response, it's usually a language barrier, no worries there, just try to keep the ship piloted correctly and do what I can with what I have.
A lot of what Surrette said is dead on what I do as well. I find it huge to explain tactics to the people I'm playing with and to admit my mistakes after I made them so everyone knows hey, the captain screwed the pooch that time.
I also inform them what my ally captain is doing, or intends to do, and encourage they apply any wisdom they may have to the situation, though I do draw the line when suggestions become demands. Ultimately, I'm flying this boat, I'll make the final say, though I hope that decision is informed with good advice.
