As Snowyowl as suggested on the suggestions thread, there needs to be a regular interval for turns.
Here are my ideas:
-Turns can be started by anyone, once the appropriate time is passed. The same thread can be used, but clearly indicating that the next turn is started.
-If you miss a turn, thats ok, just do your actions for both turns.
-If the mod wants something special, the mod should reserve the turn post, and post the special thing when the turn begins.
-The schedule should be over-ridable, for turns in which lots of action is occuring, or there is some other important decision.
