We should likely set some rules in order. And please do your best to follow them or I shall suffer the mighty displeasure of being forced to summon Rattlesnake Jake to enforce obedience.

One: No bullying other roleplayers. If you are unpleasant or offensive to a fellow roleplayer for no seeming reason then you'll receive a warning. Continue with the unsavoury behaviour and you'll be banned

Two: Be considerate of your fellow roleplayer. If they tell you to avoid a certain theme or trigger, then respect their wishes

Three: Please, no omnipotent characters. In a gunfight, don't have your character amazingly dodge a thousand bullets whilst languidly sipping a pina colada. Even Rattlesnake Jake betrayed fear when threatened with death.
Likewise, don't kill off somebody else's character if they haven't expressly given consent. Also ask and receive consent before you majorly wound also

Four: Behold my generosity! There is no need to pounce upon cannon characters before they are all snagged by similarly eager rivals. Basically, even if Rango is being played by somebody already, you can still play him if you wish. You'll simply roleplay with somebody who is roleplaying as someone else or as an OC.
But there will be a page keeping track of who's playing who

Five: Please do your best to fill in the entire OC form

Six: The password is 'it only takes one bullet'

Seven: I think that is all! Please do endeavour to have fun here!
