Late but updated 26/09/17. A full list of what should be included in screenshots. Section 4.1. The update does not only stand for Illegal factions, it can be used by any type of faction. Of course, it is up to your own discretion as a faction leader what is posted on your topic, these are suggested guidelines.
Every screenshot posted on the topic should include at least one of these points:
The screenshot shows a meaningful development within the faction.
The screenshot shows a meaningful development of your own character.
The screenshot shows a meaningful development of another members character.
The screenshot shows an event that happened with the faction.
The screenshot shows an event that the faction got involved with.
You should not:
Post screenshots using /do as NPC's or rping another character(real or not) through /me's created on a 3rd party program. Keep your roleplay to actual /me's that happened in-game.
