I ask for one in character post per weekday, one per weekend. Even when your character has nothing to say or do, a little post can make a big difference. It prevents the table from stalling, wondering whether you need more time to post. For example:
Skug pulls out a dagger and begins cleaning his filthy, fungus-riddled fingernails.
Yliss waits quietly, curious what his allies will tell him to do.
Outside of combat, a spoiler is only necessary if rolling more than one check, but during combat, all mechanics should be behind a spoiler, with all actions explicitly listed, including weapon and damage types. And links are a nice bonus. The clearer you make things for me, the more time and energy I have to be creative for you. For example:
Free Draw a weapon
Swift Activate judgment (destruction)
Standard Attack (red)
