I think what people need to keep in mind that are considering joining in the forum orgy is that it's not simply an excuse for some mass cybersex. If anything, it's a joint story, where everyone will contribute to creating it. As well as have lots of sex! For those who weren't around during the last forum orgy, they might not realise that rules are essential for its smooth running. Without that, someone can post weird, disruptive posts that utterly ignore all the posts that precede it and cause confusion. Which is why I dropped out of it before, because that happened and it just stopped being fun for me.
The orgy will work if the people contributing treat it at least semi seriously, and are prepared to make a bit of an effort. Nobody will expect works of genius, but they will expect participants to have fun with it though!
For myself, I'm the shy, nervous sort - it took me a while to build up the courage to join in the last one - so hopefully enough people will decide to join in to get it started, and I can see how it goes and decide then whether to join in. I'm not sure yet.
