Doesn't stop the massive amount of complaining when someone messes up.....you could have a message pop up 20 times saying "are really sure you want to do this?" and no doubt someone will say yes to all of them and then complain on the forum saying there should be more measures in place and such and such is scamming them by not giving it back, etc.
Its a good idea as other mmo's have it....but should this game really have it??
the system already exists, sort of... just buy an apartment and shopkeeper, then put your 'friend' on the guest list so they are only one that can access the place other than yourself...
IMO it should be monetized in some way related to crafting. Crafters can create "Mail Robots" that decay a flat amount when you send and receive mail upon confirmation.
Convenience needs to come at a cost in EU, if we want to keep the economy rolling.
I like the idea of being able to mail people items like I did in other MMOs. MA could always add a fee like the auction does for delivery. Would be nice if they actually put in the transport missions too while they are at it.
