Mailbox Space

I, and many others, often have issues with messages space. This gets annoying though I understand why it needs to be limited.

I suggest an extra that would give us extra space. It'd cost x number of bones (and be in the drop down area like if you buy dog slots/upgrades with bones) and give us, well, extra space for messages. xD

It shouldn't be unlimited or be an extra that you can purchase repeatedly to stack as that could eat a lot of server space eventually, but perhaps it could be a one time extra that could allow our mailboxes/space to hold up to 1000 messages. (or something along those lines)

Support? :-D
