Shipsets...an area of confusion for me!

[tbontob]

I am confused about shipsets.

For 4 months I have been playing 4 PBW games where the avatar of some players keep changing from turn to turn.

I do know I have to download shipsets for the players whose avatars keep changing.

And that is the extent of my knowledge. I have no idea how to do it, where to put them etc.

So, can someone tell me in easy to do steps, what I need to do to get and install the required shipsets.

Please treat me as an utter greenhorn in this. I really have little idea how to do it.
