Now, I already know what all of you are thinking, so let me address that first:

I know you can pretty much do everything and anything with a single character, and there's no need for alt accounts on the same world. I got no answer for that, other than I like to try different characters and settings.

Anyways, the main question of this topic:

Is there any way to transfer items between characters on the same account? You cannot send friend requests to your own characters while they're not online, and you can only send mail to those on your friend list. This has probably been asked before, so any information would be helpful, thank you.
