I'd write this, but I feel like someone with more server admin experience would be more qualified. Some quick and dirty instructions for operating the server as stably as possible; taking into account things like:
System service execution of a virtualenv containing evennia
Memory maintenance / ulimits / server reboot schedule
There are a number of client-side settings which are currently hard (impossible) to discover, since there's no documentation. An easily toggle-able settings tab would be nice to store these and future settings.
In the config files for sshd most lines are commented out and show the default values. This is a good way to tell the user what the default values are and help them keep track of what they've modified.
