I need to detail rules for it. Proper nouns and very specific references are not possible for the most part, unless very specific to the concerns of the organization... the meeting place, the plan (that we are following), the back-up plan... you can't refer to specific individuals, unless it is determined ahead of time that the person in question has been designated by a specific code ahead of time... which I'd need to be informed of.
You will have an affiliation score as per the PHBII. Yours will be treated as a racial affiliation, which gives you more influence. Still nailing down details on that.
