once a day if not more. If you have abilities that interrupt combat (like Step-up) plan on posting even more often.
Play your character
Have fun! Enjoy your creation. Listen to the advice of others, but do what you want. However, be sure to play your character as built. The 8 Intelligence fighter should probably not be figuring out the puzzles. The 7 Charisma dwarf should not be the lead diplomat. Feel free to assist (especially out of character), but remember who your PC is.
Play your own character
It's fine to make general requests, ask for a flank, suggest a tactic, beg for healing, but refrain from "Next turn you should cast bless, pull out your mace, and take a 5' step to the north to give me a flank." Just because the PC is an ignorant clueless snob doesn't mean the player is. Their motivations might not be the same as yours. They might not care at all about the law and/or the greater good.
Don't play NPC's or other characters
You control only your own actions. You might think your diplomacy roll of 20 will make the lady swoon, but maybe it won't. There are things going on behind the scenes and I will not reveal all of it. NPC's lie. I know this might be a shocker, but it's true. I will be honest with you as the GM, but NPC's might actually deceive you.
Try to advance the action
PbP is slower than desktop gaming and as such you should be active with nearly every post. Before pressing submit, consider whether or not your character is actually doing anything in your post. If not, you may want to reconsider. Naturally role play is doing something as surely as any action.
There are no real world rewards or prizes for winning. I'd much prefer to stab you in the heart with my sharp wit then kill you with a dragon. If your character dies, then they have more character. They'll make it back to the world somehow if you want them to, or we can try something new. If you're not having fun, don't cheat to fix it. Talk to me.
