Liberally adapted from others who do this better than I do, since this is my third PbP seat in the GM's chair:
* I prefer the use of [ sblock=OOC ] instead of [ OOC ]. It does a better job of hiding the 'out of character' commentary.
* Group initiative, rolled by GM. In the case where an individual member of the 'losing side' rolls better than all other individual members of the 'winners,' that character may act first in the initial round of combat (surprise or round 1). Otherwise, unless a players specifies that actions are to follow another character / event, actions happen in the order they were posted. More than 36 hours or so delay for posting during your turn in a combat may result in my NPCing your character to keep things moving.
* Feel free to use Invisible Castle or the EnWorld on-line dice rollers for your characters. In general, I may or may not be posting my actual rolls, or just results. I may use the EnWorld roller more than other GMs, so if the dice at the bottom of a post starts overwhelming, you can shrink that down to a text one liner by changing your user settings. Settings->Edit Options->Thread Display Options->Dice Roller Display->Streamlined. GM secret rolls like Perception and Stealth will usually be done by physical dice.
* If I need a knowledge check or perception check from a character, many times I will roll it for you and post the results immediately instead of asking you to roll, then waiting a day for a response, then posting the response to the roll. This is intended to speed up the game. Examples: Kn Nature to know you are fighting a shambling mound. Depending on what I rolled for you, I would include a spoiler block for the individual character as to the pieces of info he knows for battling that type of creature.
* I tend to post at any time of the day or night. I may post "mid-round" combat updates as needed or "short responses" to questions more often than the characters. If you're going to be away for longer than a couple days, please let me know if at all possible so we can arrange NPCing if necessary. I will generally look at your wiki character sheet for a "Intended next action" or "Standard Operating Procedure" near the top of the sheet for clues as to what to do.
* If you do not post for a week or more without notice, I may end up writing you out of the adventure. You will still receive your share of the XP and treasure earned as well as time XP and gp to the date of your last post.
* If your character gets enough XP to level they may do so at the end of an encounter. This grants the extra hp, but does not heal damage, and grants any additional spell slots, but not spells prepared. A caster capable of spontaneously casting could use these slots normally, a cleric could only use them for cure or inflict spells, a druid for summon nature's ally, etc. Prepared casters may prepare spells in these slots as if they had left the slots blank for the day, if they are able to do so. They can go through the appropriate spell preparation as if they had already rested if applicable. If you are adding a new class that requires special materials, like a wizard's spell book, please PM me a little ahead of time so I can work it in cleanly.
PS: My PM box hovers at 16 of 20. Too many projects I have to track.
* Mini stat blocks (preferably including a link back to the wiki page for your character) and a picture for maps are quite helpful. It is nice if you can colorize the major stats like Total HP, Current HP, AC, Weapon in hand.
* If you have an interrupt or immediate action ability, please list it in your mini-stat block so I can attempt to weave it into the bad guy's combat at the appropriate time the first time around. If you can take more than one AoO in a round, please list that too.
* I mess up sometimes. Everyone does. Feel free to point it out. I will try to retcon to fix if needed. Sometimes, I will need to use the "plot device or special circumstances overrides the normal rules" card. We're all here to have fun, so I'll try to do everything I can to facilitate.
* Sometimes I will earn the "cruel rotten bastard" title. There might be occasions where the cause
has to play out for a week or two before you see the effect
later and go, "Oh, that was worth it." I promise it will never be personal.
* This adventure is based on Wizards of the Coast's 3.5 Wreck Ashore.
I am just mentioning it so no on joins a table top version of that game and then realize, "Oh, I am already playing this one."
I think I have overdone it by now, let's get started.
