Speaking of trade we need to be able to mail more than one of an item, or get a trade GUI in there somewhere.
On a technical aspect of this, an NPC mediator can be used, when you speak to them it comes up with a listing of all players currently talking to said NPC, you can click on one to request trade, then if they accept it pops up the trade GUI for the two of you and you can trade larger amounts of items/gold through this interface. Yay for random NPCs'.
Aaaand we're back to houses again it seems, so I will post on it as is my fashion. For housing I like the idea and Badspots post seems to put him as a supporter, but I think that just telling him we want houses is'nt going to work, at least come up wit a way to put it in. Should the houses be like the shop? Should it be a neigborhood or are they all separate? Perhaps they will be in some ridiculously far away repeat? Ideas people. I personally support a neighborhood but with a lock implementation to keep people like spoon and gristy out, that would give you a way to do larger trades as well.
