how storage agent works?

hi i have
1 account (1 cd key) 1 copy of guildwars
3 characters under the account
how come all 3 character share the same storage box?
and what else is shared other than the storage box ?
thanks

so you can give your mighty staff of smiting your warrior character found for example to your monk character

all characters on the account share vault space and also guild affiliations

is that the only 2 things are shared to all my char under one account ?
or there is more to that ? what about gold and stuff (items)
thanks for the reply!

The storage with the storage agents is account-wide. So, if you put a smiting staff in your storage with your elementalist, you can log off, log in with your monk, and take the smiting staff out of storage with your monk.

There is no way to share gold with all of your characters on the same account at this point in time. You'll have to get a friend or a guildmate to transfer for you.

Don't forget friends lists are also shared

Any items (if that is the "stuff" you are referring to in the above post) can be passed from one character to another as long as you have an opened storage account with that character (50gp). As far as I know gold is not shared between characters. That is an individual accumulation that you gather as you move around throughout the world.

so the only things that shared under 1 account are storage agent(all char must pay 50g to share/access),friend list, and guild affiliations.
any more?
cause im sharing this account to my little brother.
thanks guys for all the reply!
