It might be fun and helpful if we had a section where we could put up trade ads that everyone in the game could access.

Say you need a containment cage. You would go to the "bazaar" section and look to see if anyone was offering to trade one or several. And if you didn't find an offer then you would put in an ad that says, offering 5 crimson obelisk for 2 containment cages (or whatever other artifact or credits your willing to give in exchange). To prevent too long a list of trades, everyone is allowed to put in 1 trade ad every 12 hours. And the ad would last 24 hours.

I have suggested things like this before, and most people said my version would make people too strong too fast. However, it would be cool it you could trade artifacts, or buy/trade things. Trade a Vortul blast phaser for a terraformer or something like that.
