We have had an upgrade to our in game messaging system.
Now, when you send a message, you enter the recipient and subject and it’ll put you into a buffer, where all the usual /s, /l, /n, /f, /a, etc all work. When you are done, /s to send and viola. You can send a multi-line message with colours.
The server checks every 60 seconds and lets you know when a new message comes in and you can view a list of messages currently in your inbox with message check. To view a specific message in full, you now have to use message read [id].
Still a (little) buggy and there is still more to come.
