Alpini,
As you pointed out, you had control and put it to use for the benefit of the country.

I am glad that you posted, especially since that is not always the case unfortunately, and I won't carry that conversation any farther than to say that HTC does have a firm handle on those that don't play by the rules.
I wasn't there, and only ask if a little more communication during the game could have cleared things up faster? Also, rank in AH does not always encompass wisdom. Heck, I look at my rank sometimes and go pffffft, that number ain't gonna last long
Basically, I agree hiding a fleet is both a tactical plus if it helps win the war, and a tactical error if it needlessly hampers gameplay of the country owning it. A good line of communication, if ever brought into question again could be along the lines of what you stated here. "I am skipper of the fleet, I am keeping it safe and bringing it into use against OUR enemies." Then the only viable counter arguments, would have to along the lines of let us secure its port first, or I urgently need it to land damaged or fuel limited aircraft.
