1.) Excessive OOC is bad: One of the most annoying things in TK and other free form places is when a room becomes a huge OOC debate which scares away newcomers and anyone who wants to RP. If you enter a big OOC conversation with people in an Order room, then go to the lobby with them.
2.) Roleplay Realistically: I can't stress this enough, Most of the roleplaying is in a free-form, unmoderated fashion (Unless you're using the BCS rules, see next section). In other words, being a respectful player is the only key to progressing and creating storylines. As a member of the Order, you're expected to be a little higher up on the courtesy scale then everyone else; which means you're not going to mode out and ignore a hit if someone tries to whack you with a stick, and you won't drop anti-gravity bombs in pubs and destroy the world after unleashing a plague of gnats, or other ludicrous actions.
3.) Don't destroy the flow of an RP: One thing which murders a good RP session is chaos. Automatically, after you post, you're in a line and you need to wait for your turn to post again. So, pay attention to who's in a room with you and when it's your turn to post again.
4.) Don't destroy the posting order. This is defined by taking four hours to write an action and, by the time you're done, everyone's long gone or asleep. I understand you might have a specific style that takes a long time, but there's no requirement in taking all day to write an action. If I'm moderating the room, I WILL forfeit your turn if you take all night to write something. A post doesn't HAVE to be ten paragraphs long. Shorter and sweeter is almost always better and it keeps things flowing.
5.) No Arguing OOC. In my experience TK has an enormous problem when fights are handled in an unmoderated free-form style. it dissolves into a frenzy of bitching about who-hit-who first and whether attack B was realistic because attack A had a forcefield on that reflects bullets. If the RP gets this complex, odds are you might be breaking rule number two as it is. If someone else chooses to take things OOC and fight endlessly, then try and resolve it ASAP. If somebody starts incessantly whining OOC in a guild room, have the person kicked or simply ignore the player altogether.
6.) Stay active, but real life comes first. I myself am a college student with a social life and an often busy schedule. I get on TK a lot during summer break in the evenings or at night. I'm not always around to regulate things, and as such you're not expected to have to devote your life to a game guild either. However, if you're completely nonexistent you'll be taken off the roster. You can pop back in again, and it probably won't be a big deal. But, if you don't think you have time for any R&R at the computer whatsoever, or if the guild simply doesn't interest you at all, then maybe you shouldn't join in the first place. An ideal goal of the guild is for it to reach a point in the membership where it can self-govern itself just through active members and storylines.
7.) No harassing. Storming a room in a in-character fashion is fine, but if players begin to express discontent then you have to be courteous and leave if they're not having fun.
8.) Don't take grudges OOC. Things should stay inside the game, and OOC talk on AIM or wherever should be the place to chat about the happenings in the game world in a relaxed fashion, even if it's with your enemies.
