A while ago a player asked if I could add the ability for players to exchange CraftyCredits. It's been a while since then and I'm glad to say you can now trade CraftyCredits in the trading post!
You can trade in 1x, 10x, and 100x increments. Right click the sign of your choice and it will transfer however many credits to the other player. Credits are pulled from your balance and do not affect your total credits/votes.
