Alright, tried a search for this and didn't see anything....

I know I can mail items to myself (apparently not credits though...). The question is, if I mail items to myself, how long can they stay in my mail? Does the mail system eventually time those mails out and just delete them? I'm using the mail system to send items to my joined trill alt that I'll roll on Tuesday, so I really don't want to see everything disappear all the sudden.... :p
