turn the jewelry again.

check out the PREMIUM verb in game. I have also expanded the premium page on KP a bit this year http://www.krakiipedia.org/wiki/Premium

Welcome to Premium!

If you'd like more information about Premium membership, you can type PREMIUM in game and see a list of topics. Then either click the link or type PREMIUM 1, PREMIUM 2, etc. to see the information!

You can always post here with questions as well.
