Fencer, how about modifying the Message box so its the same design as the Notepad.
In other words make Archive & Outbox Tabs and the option to create other Tabs possible. That would be great and very handy for keeping certain messages where we need to get to them (e.g. Fellowship ones, Tournament ones etc...).
Having an edit button could also be useful as i am sure we have all sent messages (with Links) only to find out they dont work, having the option just to go back and edit them correctly and resend would be nice.
