Who stole the mailbox idea?

[Admins]

To be true, I didn't know that any playerworld had mailboxes or letters. I haven't seen it on Gaia, have only played a few minutes on it. So I am sorry if someone thinks I 'stole' something.
Actually the mailboxes are in the mudlib for more than 10 years, I thought its a good thing to add it to Graal now since its good for role-playing and the new house building thing, where every house owner should have his own mail box.
