I think I know what you are talking about, and I have personally tried that, which gives a nice overwiev of the site true enough, but also it forces people to stay here logged on for several hours, if you want to make any roleplay at all. First of all, it isn't always that there are two people online at the same time, and second then people leave the thread once they log off, which means you really can't have much of a life at all.
With this way, that makes it a little "crowded" One can log on and begin a thread, just to log off again and the next day when they have the time again, they maybe have an answer, and so the roleplay can begin without thinking about such things as time and stuff.
Thank you for the suggestion, and some boards are doing this, just not people like us. This way also gives people the time to write long posts, and take their time doing the best the can possibly do.
