1. Godmodding - The most obvious. As I said above, you can be all powerful but your powers cannot be used to an extent that it exceeds any other characters. You may not kill any powerful NPC in one move, nor a fellow RPer (unless agreed on). Also, you can't dictate. This means that if you battle with another character (not assuming your RPing an all powerful character, this goes for all) you can't decide the attack outcome. E.g You can determine the attack, but the attacked RPer must determine the outcome if it directly effects him/herself.

2. OOCs and Discussions - Here's a nice quote I got from a very wise forum admin a couple of months back: "Attack the post, not the poster" - Cool eh? Well follow it. If someone says something, attack what he says, and their judgement rather than the person themselves.

3. Follow RP Rules While ICing At All Times - In Getting Started forum, post three there's some RPing rules. Follow them like the bible.

4. Follow these like it's your bible - Basically, if you follow these rules RPing becomes much more fun for you and everyone else. It only takes one bad post to spoil a good RP.
