1) Don't god mod. Whatsoever. Your character is not Deadpool, and can't physically read the lines that the other rper types. This doesn't even have to specifically be in fighting. Let's say player A is a theif, and in player A's post he/she states that his/her character is planning to rob player B. Player B's character can not immediately say "You're not getting my money" or immediately Sheild his/her wallet. That's godmodding. The same goes for fights as well, all forms of godmodding/metagaming are not acceptable in any way, so don't do it.
2) Please please please PLEASE be descriptive, and post at least a few sentences per post. Paragraphs are preferred but we all understand that every once and a while posting gets hard, but we ask that you please be as descriptive as possible and post as much as you can.
3) No mature "Rated M+" content. This is an absolute no. While yes, there are certain exceptions to this rule such as Player A making his character an extreme pervert, so he tries to grab Player B's butt or something. Perfectly fine. Another exception? Being naked. That's also perfectly fine. Everyone has a body, it's not like one female is different from another or one male stands out, so it's fine. Anything too in-depth with detail will have THE POWER OF JUSTICE brought upon it.
4) Simple little thing: Don't speak in first person. You're character is not "I" your character is "He" or "(Name)". Either speak in 3rd person or 2nd person, never first UNLESS it's dialogue. If player A says "Hi my name is John Doe" in dialogue that's fine.
5) There is a post order in every topic. Don't forget it. A common problem with post order is if someone doesn't post as fast or someone comes in in the midst of a topic. For the first problem it's simple. If a player takes over 24 hours, skip. BUT the order is NOT to be disturbed. Once their turn comes around again, you must wait another 24 hours. For the second problem it's simple. Redo the order. If player A and player B start a topic together, then player C comes in BEFORE player B posts, the post order changes from "A, B, A, B" to "A, C, B, A, C, B."
