depends whether you want the Viceroy armour or not. If you do save them as you will need 3000 cans for one of the hand ins.
If you are not really interested in Viceroy then sell them on auction. The MU is indeed very nice :)
I will of course be there. :)
As an added note on the passport chain, when you hand the sweat in you get an achievement which we all see, so we know it has been done.
I would suggest making it a requirement to have achievements public, so the MVSTs can check to see the avatar doesn't already...
Some texture BPs for the Monrian skins so people can have yog/shog/shub textured clothes and vehicles. Think this would be a popular introduction and give more uses for the skins which are mainly TT food atm.
