Hello,
Tremulous plays in a cruel and unforgiving world where racism is on the everyday agenda on both the human and alien side.
This is terribly old fashioned by today's standards and I bring you the idea of:
The Love Hour
One hour each weak, on all servers, aliens and humans gather in a central map location to show their will towards racial tolerance and even friendship. They don't attack each other, but have a peacful chat and stay. Dretches should take care not to hurt humans during those meetings or should generally chose the more interracially accepted granger class.
I suggest sunday evening for the Love Hour because on sundays people usually are in such a peaceful mood.
