Rules may be updated every now and then, so check back once in a while to see if anything has changed.
If you don't want to read everything, the basic rules are underlined so you can find a specific rule you may be looking for.
Don't be a dick. Want to go into the Introductions section and insult someone because a goat is their favorite animal? Don't. Want to say someone's suggestion for a lightsaber is a bad idea? Don't. Sometimes you might just need to watch your wording, so instead of saying, "That makes no sense since this not a custom server," you could just say, "I prefer to have items in the game that are normally in rs," or don't say anything at all.
Don't spam. There's no need for you to make the same post over and over again, whether in the same section or different sections. This goes for both your posts and others'. Don't bump any threads, since it will just be considered spam within a thread. If a thread is important, then I will pin it.
