In your travels you will find blue sign post such as this:
These signs can be found throughout Temuair at the different religious
temples; outside the town centre; or on the side of the road.
The signs allow you to send and read messages to and from Aislings. If you
double click on the message, a window will pop up:
Most of this is self-explanatory, but here's a quick introduction. To send
messages, you click on New. New messages from other Aislings will appear in
yellow on your screen; a selected message, in blue. Double clicking on a message
will open it for you, allowing you to read it.
You can also send personal mail. To do so, go to any shop, and click the
bulletin icon. The look and feel is the same as for the bulletins.
