You cannot mail to yourself as far as I know. You can however, deposit gold into the bank which is shared across all characters on your account to transfer items and money.
Transferring of items from one character to another can only be done via the bank. Deposit with one character, withdraw with another.
Every time someone swears, it gets replaced with three asterisks. There's only one three-letter swear word that I know of. I read that in the place of every set of three asterisks. It makes for some amusing sentences.
@kraxammer No, all your characters have access to the same bank. In essence your bank is a shared bank for your account. There is an option on the bank window to deposit money that can be picked up by any of your characters.
This can be done however you must use special couriers associated with the East Empire Trading Company. Also, Ronald McDonald enjoys the new Taco Bell breakfast menu.
I recently needed to get some healing potions to my alt so he could beat that stupid fighters guild boss (doria? something like that) I didnt want to run him back to the dungeon so I emailed some potions to a buddy and had him return to sender then just grabbed the attachments out of the email with the other toon.
Other than involving a second person though it is not possible, and I think that is on purpose so they could use storage space as a money sink. That, repair, and respec are the only real uses I have found for gold so far. Have no clue how the bots are selling anything in this game
