If you just started the best thing is to open up a few diferent browsers (IE, Netscape, Opera, etc.) and create different accounts and start chatting between those fiction charactors. I suggest different browsers because they store cookies at diferent places. This only needs to be done at the the first days or weeks -depends on how many visits you get, people like to see the place is active. If there is only one or two posts you wonder if it is worth it, after all, who is there to reply? Once people start seeing their replies get answered, they will come back, others will notice, and will post as well...
