It should be noted that just posting "Hey, I'm in the mood to roleplay!" over and over again with no ideas or effort is not really acceptable.
Many people post a copy of their request thread - with ideas, details, etc - in each request forum if they're interested in either form of RP. This is acceptable.
You will not find every rule codified and excruciatingly detailed, here. While mods are available to answer questions, we don't try to cover every single eventuality in the rules, because a) it's impossible and b) it makes the rules labyrinthine and incomprehensible. This is something with which you will have to learn to cope.
