Personally, I think it is a little wrong to change the story also. We are on our 17th story and we have never really had a problem. Whatever way it starts it should continue and not be changed for someones liking (sorry Veeki and Komal).
Everyone should feel welcome to write what they want. We do start a new one every week. And at this point almost every single one of you have one or more RM FF's that you started on your own anyway so you can express yourselves there as well. This is supposed to be fun for everyone so just roll with what you get. And these were always repetitive in the past. You can always change things up a little. Thats the point of it. I just don't want people to feel like their ideas are wrong.
Like I said.. do whatever you want.. just take other people writing into consideration..
