Yes. Definitely. Set all mines to stockpile. When you decide to arm a minelayer, turn stockpiling off for that type of mine, rearm it, then turn stockpiling back on. Only rearm a minelayer when you've decided to conduct a minelaying mission. Also, try to keep an ACM in your ports that have defensive mines.
I have been inputting my orders for the campaign game first turn since July 4, 2009. I'm getting close. In another month or two, I might be able to run the turn!
