This system is basically the general "Buyer" mode I've suggested for Retainers on the Marketboard. My idea did not include limitations (anyone could sell to a Retainer in Buyer mode, just as anyone can buy from a Retainer in Seller mode) and I really see no reason to include those here. If someone is looking for Airship materials for a FC Airship, does said individual really want to limit himself or herself to what FC members are willing to provide, and not what the server in general may be willing to provide?

Buying is part and parcel of any sales transaction. The Marketboard needs to have a means where people can offer to Buy, as well as offer to Sell. I suspect some people will be amazed at how much prices will actually stabilize for those items that actually move frequently should they institute a Buyer mode.
