I've seen this in other MMOs and it is very nice to have.

The concept is to be able to list items on the MB with a flag that only people in your FC can purchase. These items would not even show up in a search by someone outside of your FC.

The point of this proposed feature is to allow FC members to supply items to other FC members without the need to use the FC chests (which are limited in size) at a steeply discounted price. It could be 1 gil. It doesn't matter.

Here's an example:
- Let's say someone crafts full sets of DoW/M gear and they are happy to let it go to any member, but maybe that member isn't online right now. Maybe this player logs in, goes to buy a Body Piece of Fending and sees the first entry as discounted through the FC. They buy that one.

- Another example, someone is crafting stuff for their crafting log completion achievements. They have a ton of stuff to dump but don't want to necessarily crash the market and don't really care what they get. FC members can buy up cheap potions, housing items, gear, glam, etc

Maybe it could be extended to friends list as well.

A possible drawback is that someone could just buy up your FC-only item and relist it. You'd like to think that if that was discovered, that player would just be kicked from the FC.

Maybe add a flag in the retainer that only people of Rank X in your FC can do it. So new recruits are excluded.
