Here are the current rules:
1. No pornographic/inappropriate images, please.
There are people aged under 18 here, you know.
2. Only talk in a way that people can understand.
No leetspeek, and no "U NUB I WNT 2 KIL U".
3. No sexism/racism/fascism/prejudice etc.
No "STOOPID JEW LOLOLOL" or "UR GAY LOLOLOL". This will get you a very quick ban from me, fools.
4. No hacking other people.
This is illegal, you know.
5. No impersonating admins/anyone else.
Roleplaying of course is allowed. Impersonating a fictional character is alright as long as you do it well. For instance, "I AM THETIS I USE MY 500 ICE DRAGONS TO MAKE YOU DIE" or "I AM ATLAS I KILL THE PEOPLE WHO POLLUTE THE OCEAN" is not good roleplaying.
6. Not a rule, but, if it weren't already obvious, no admin or moderator will ask you for your password. Do not give your password to anyone.
7. Obey other smaller section rules where they apply.
8. Use common sense. Some rules are not stated here which it should be common sense to obide by.
I hope you all enjoy your stay at ZX Exchange!
