One of these is your Message Centre as I will call it.
At the moment you have a simple inbox that you receive everything in, and when it is full, it is full and you have to delete stuff.
This can be filled up by Admin messages, Commander Messages, Private Messages...
I think that perhaps it would be handy to have it organized into tabs..
- Messages from Admins - To be in its own section on your Message Centre (possibly an option to acknowledge so it hides)
- Server Notifications - Have its own tab called "Notifications" or something
- Commander Messages - Have their own tab called "Commander" or something
- Private Messages - Simply "Inbox"
- Outbox - All your sent messages
There are ways this can be expanded, but this is the basic idea i have
