I'm not going to get too fancy with the general posting requirements. As is fairly standard:
Bold for speech ("Hey, what are you looking at?" he snaps at the Rodian.)
Italics for thought (I wonder what that could be...?).
And plain text for narration, in the present tense.
There will be a dice rolling thread for those who wish to use it, particularly so you know if you need to narrate a success or failure.
If you opt to roll your dice in the dice thread, indicate your result in your post, with a link back to the post in the die rolling thread you made. A fieldset at an appropriate location in your post works great for this.
I know that it can be hard to think of much to elaborate with on your post sometimes (been there, done that). Also, I'm aware that sometimes you just don't have enough time for a long post. Still, if you can, try to put enough into your post to get it longer than a couple of lines. Two mid-length paragraphs (a few sentences each) is always a nice post length if you can't write me a book.
Languages other than Basic
For the most part, it's fine to just go ahead and say what is said and in what language. This is, of course, a cooperative game and so I don't expect players to be keeping all that many secrets from oneanother. Sometimes though, the impact of a post is lessened if a non-Basic language is simply posted as normal. In these cases, break it up with a description of your speech and then a fieldset showing what the Basic translation is, or in some cases even secret text to those who have the language
An example of the former:
He speaks sternly in Dosh, pausing briefly before finishing and then staring coldly into the trandoshan's eyes.
Much more dramatic-like, isn't it?
I do want to keep track of ammunition to keep with the spirit of the game. At the end of each combat post if you could just note your character's ammunition supply using brackets to represent individual power packs or slugthrower magazines using [X] to represent a full magazine or [#] to represent a power pack with # rounds remaining, like so:
Loaded:  Extra:   [X] x3
Which would indicate that the loaded power pack had 48 rounds left, and there were spare power packs with 39 and 27 rounds remaining, as well as three more full packs. If you use two weapons that have a different amount of charge per full power pack, feel free to ease up bookkeeping by using two such lines, one for each weapon.
