Topic: Differences between 2nd and 3rd edition

Hello,

I recently purchased Grand Fleets 3 and I noticed that it is not listed in the boardgamegeek.com database.  I am currently adding it to the database and the moderator has asked me to give some of the differences between the 2nd and 3rd editions.  I have never played the 2nd edition so I was hoping people could give me some of the differences so that I could finish the entry for Grand Fleets 3 over at BBG.  Thanks!
