For everyone asking all these questions, nothing has changed since I was a CH over a year ago, maybe longer.
The general expectation that is expected of a character background, as was taught to me is "who is your character, where are they from, why did they come to Chernarus, and what have they been doing since the outbreak began"
No WIP pages are allowed to be set as an active character.
Failure to follow up on a CHs requests to you will result in a temp ban.
There's details I won't go into due to staff ToS, but I can assure you no one is singled out.
