General etiquette I haven't covered, but this is my normal "How I do PBP stuff" primer for my games:
Some of the other bits you've included in there I wouldn't mind thieving and sticking in the below post (namely the posting outcomes, social contract, etc)
Your characters actions are posted in unadorned plain text. I try to keep these in third person, present tense.
Your speech is done in bold text.
Quote:The towering man draws the massive sword from his back, setting his stance against the upcoming rush of kobolds.
Internal thoughts are handled through italics.
Quote:Come and taste my steel! the barbarian growls, feeling his rage flow through his veins.
Information about the spell you are casting in red font. I also try to include a link to the spell in the post, but I don't ask you to do that if you don't want. Just a quirk of mine so I can get to the spell details quicker.
Quote:Dirty kobolds. Vile creatures. I would as soon bed a devil as I would to see a single of these vermin roam free. the sorcerer thinks to herself as she feels the wisps of poison start to coalesce in her hand.
Quote:Casting poison spray. DC13 Con save or take damage.
Anything out of character is posted using the OOC tags.
DM Information I try to post in this color.
OOC:The barbarian really hates kobolds. I'm not sure if this would give him any kind of advantage on the strike? Are there any other rolls you want to see?
Quote:Feel free to roll a Nature check to learn more about Kobold lighting preferences. Billy, do so at advantage because your mom is a kobold.
A few housekeeping items, so you all know what to expect:
1) Given the nature of PbP games, I will roll all initiatives. Typically combat will be side based, meaning all the PCs will go in one batch and then all the NPCs will go in one batch. In order to keep it "easy" to understand, I'll post the current combat lineup in Bold Teal. If your name is in bold, you are free to take your action. If not, no action for you!
COMBAT! Bold below may act:
Army of Grifters
2) Please roll attack and damage when you declare your attack. If you roll a 20, edit in an extra dice for the crit damage. For example, make a roll like: Longbow Shot: 1d20+3, 1d8+1.
3) If you think your action will need a roll, post it. If I don't need/want it, I'll just ignore the result. :)
