A big part of this site is death. If you're not comfortable with killing any of your characters, you should probably give up now. There is a two character limit per player. After kicking the idea around for a bit, the staff here at RtR would like to suggest that you have one character that you want to develop and keep around, and another to satisfy the general bloodlust.
Two characters, and this is a rule with one exception- Character of the Month. If you win it, you get permission to make an extra character. This does not change if you win more than once- you get more characters every time. As well as the extra slot, CotM winners are allowed to create a character from our exclusive list of government officials. Those guys aren't to be trifled with.
We don't have any inactivity rules, either. Be as active or inactive as you please. Just don't miss the periodic role call and you'll be fine.
Rules are subject to change, and that's why I've left them kind of vague in the first place. Just keep your head on right, try not to troll up the drama, and nobody should have any problems. It's all in fun. But you knew that already.
