While this page is primarily intended for guiding a submissive or a slave in their "online conduct" or "behavior", you'll find these things can actually carry over into real life.
Whether you are a slave or a submissive, you'll always be expected to show courtesy and respect to anyone that you encounter online, especially if you find yourself in the company of, or talking to a Dominant. Remember, if you embarrass yourself, you also embarrass your Dominant. The quickest way to find a novice sub is to watch for the lack of respect she shows to a Dominant in a chat room. A submissive or slave may not like a Dominant she comes across while she's chatting, but that is still no reason not to be courteous and respectful. And yes, it goes without saying, as a submissive or slave you are also due appropriate respect from anyone else you come across, including Dominants.
First things first, remember anytime you are online you have a couple of inherent capabilities, regardless of how submissive you are, you and you alone always have control of your "off switch, ignore button, and delete keys" on your computer. Don't ever forget this! Keep in mind the rule that for every 100 so called Dom's you find online, if you're lucky, perhaps one of them will turn out to be a real Dom or Master. With that, understand there are idiots and wannabe's out there. A submissive or slave is under no obligation or commitment to honor the instructions, discipline or domination of anyone except her Dominant.
As you wander around the internet, you'll find there are many chat rooms or communities that will insist that a submissive or especially a slave, seek permission to enter the room before she comes in. Often these rooms will expect the submissive/ slave to state their "asl" (age, sex and location) followed by a request to enter the room. While personally, I disagree with this practice of having to ask for permission to enter a room, it is a policy of those rooms and should be respected. Other rooms such as Asj's chat room will welcome you with open arms as you come in the room. Unless you've been to a room before, or someone has recommended you to the room and told you of the policy there, it's almost impossible to know in advance and you'll have to play it by ear.
Once inside a chat room, the keywords to remember are "respect" and "courtesy". If you show respect and courtesy, you'll soon find that you get respect and courtesy. Don't forget to greet all members in the room, not just the Dominants! It's very appropriate to say hello to the individuals there that you already know, but it is equally appropriate to say hello to those that you don't know. If it's observed that you only greet the Dominants in a room, you may soon find yourself developing the reputation as a bit of a troll.
